Why is Macron important?

  In 2017, when Macron was first elected to the French presidency, the whole world breathed a sigh of relief because the UK had voted to leave the EU the year before, and the US had just elected Donald Trump, in Europe at the time, even Sweden. Populists are also climbing in consistently sober countries such as China, Denmark and Germany, a trend that has temporarily ended with Macron’s election. On April 10, Macron will face voters again for re-election. Various polls show he will win by a narrow margin, again beating right-wing candidate Marine Le Pen. And in the 2017 election, he won 66 percent to 34 percent. The comparison of the two shows that his approval rating has declined. There are many reasons for this: the war and the Covid-19 pandemic have polarized politics, and not only in France; Macron has sometimes faced voters with aloofness and aloofness, with critics dubbing him a “president of the rich.” In 2016, Macron wrote: “If we don’t unite in five or ten years, Ms Le Pen will be in power.” One lesson he has offered over the past five years is that complex political tradeoffs can hardly beat simple slogans, the current Voters are so focused on identity that scores on jobs and economic growth are not enough to keep leaders re-elected.

when the virus remains in the body

  The attending physician at Tan Tock Seng Hospital in Singapore has found in daily cases that even after contracting asymptomatic new crowns, otherwise healthy patients may unexpectedly suffer from life-threatening heart attacks. In early February, a study published in the journal Nature Medicine concluded that there were 45 new cases of cardiovascular disease per 1,000 infected people in the year after contracting Covid-19, about half of which were severe complications. diseases, such as heart disease. Viral infections are known to cause heart problems, and even after contracting the flu, the risk of a heart attack increases significantly for a short period of time. However, the risk of heart attack persisting for a year or more after Covid-19 is a new phenomenon. Exactly how the coronavirus damages the heart and blood vessels is an area of ​​focus, said Ally, chief research officer at the St. Louis Health Care System in Virginia. “It may be lingering viruses or viral residues in the body that trigger chronic inflammation, which can lead to damage to the lining of blood vessels,” Airy said. But cardiomyocyte death due to viral infections, coagulation disorders, dysregulation of autoimmune processes, etc. It works.” However, previous research on heart disease risk after Covid-19 infection has been almost exclusively in unvaccinated people. Data after vaccination are insufficient. “Our study has not been formally published,” he explained, “currently showing that vaccination reduces risk, but does not eliminate it.” In addition, how the Omicron variant affects cardiovascular disease after infection also Not clear, even though the course may be milder, a dramatic increase in the number of cases could lead to a dramatic increase in heart disease.

Ukrainian in New York

  The heart of New York’s Ukrainian community has always been St. George’s Ukrainian Catholic Church on East Seventh Street, built in 1905 and modeled after St. George’s Cathedral in Lviv, Ukraine, but in scale. much smaller. Another important place is the Ukrainian American Self-Reliance Society at 98 Second Avenue in New York, founded in 1947 to help Ukrainians who arrived in New York during the postwar immigration boom. When they first arrived, many Ukrainians did not speak English, so the association helped them find housing and jobs, and later opened a school to teach Ukrainian history and culture. But the association’s greatest legacy may be its credit union, which opened with a capital of $316 to provide financial support to immigrants without money and credit history. Today, the New York branch alone has $1.5 billion and $15,000. members. It only served individuals who could prove Ukrainian ancestry, and the rule still applies today. The Ukrainian American Self-Reliance Association hosts weekly bingo games, English lessons and presentations for seniors, and it has a small library with a colorful map of Ukraine featuring native animals, agricultural and industrial areas of Ukraine logos and images.

  In the recent Russian-Ukrainian conflict, drones have once again demonstrated their prowess, creating a large number of successful battles, which has not occurred in past wars. Although the role of UAVs in military operations in the Middle East and the Naka conflict has been verified in actual combat, opponents in such battles often lack effective air defense systems, so it is difficult to evaluate these seemingly powerful UAVs How effective is the machine in the confrontation between great powers, the conflict between Russia and Ukraine provides an opportunity to test this matter. Although the Russian air defense system did not perform well in the Middle East battlefield, it is still considered to be one of the most powerful air defense systems in the world, because the Soviet army knew from the Soviet era that its air power was simply unable to seize air supremacy in a head-to-head confrontation with the United States. , so it is necessary to develop a strong enough air defense force to offset the air superiority of the US military. Although there is a lot of controversy over the effectiveness of the Soviet-Russian air defense weapon, it cannot be denied that it has played a good role in the previous armed conflicts after World War II, and has also achieved good results in shooting down the US F-117 stealth fighter. Since the Russian army has the most advanced Russian-made air defense weapon systems, and as the country of origin has mastered the secrets of the core parameters of these weapons, the confrontation between the UAV and the Russian army has become a test of whether the existing air defense system can be used in the The perfect place to effectively defend against drones in total war. However, the result was shocking. Even if the Russian air defense system encountered small and medium-sized military drones made by Turkey, it could not achieve effective defense and confrontation. The attack from the air caused heavy losses to the Russian army. In fact, the changes brought about by drones on the battlefield are not just for the user to obtain a cheap air attack platform. Its appearance has fundamentally changed the rhythm and tactics of the entire military operation.
  The U.S. military found in Iraq’s operations against the Islamic State extremist organization that the MQ-9’s role in urban operations is not as simple as a missile launch platform. Due to the numerous buildings in the city, it is actually difficult for traditional air and ground reconnaissance to dynamically grasp the enemy. military intelligence. However, UAVs are relatively slow, and can provide more detailed battlefield pictures than other aircraft at low speed and medium altitude, and are connected to intelligence command centers far away from the battlefield through military data links. These video materials can also be zoomed in and played in slow motion. For analysis and judgment. Compared with missile launches, dynamic real-time high-definition video transmission is the core function of various UAVs. Although this change sounds like an enhanced version of the reconnaissance aircraft or other reconnaissance platforms in the past, it has provided an unexpected result in actual combat, that is, it has completely changed the rhythm of the battlefield. In the Gulf War, the coalition forces had unparalleled air superiority, but the rhythm on the battlefield was still slow. The fundamental problem was that a lot of time was spent in the long chain from reconnaissance to killing, which was not only related to the technical level at that time. The lack of dynamic real-time high-definition image observation methods is also the key. For example, after the coalition bombed a military base in Iraq, it needed to dispatch a special air reconnaissance force to evaluate the bombing effect to determine whether it was necessary to organize a second round of bombing to ensure that the base facilities were completely paralyzed. In this way, half a day has passed, and after the drone is put into the battlefield on a large scale, the effect can be determined as soon as the bombing is completed. If it is determined that another air strike is needed, a second wave of missiles can be sent immediately, and even the reconnaissance drone itself You can fire missiles directly to replenish the gun. According to the assessment of the U.S. military, as a reconnaissance and surveillance platform, UAVs actually greatly speed up the operation of the battlefield kill chain, making the advance of war unprecedentedly fast and flexible.
  In addition, UAVs can also complete attacks that were not possible with conventional air-to-ground platforms in the past. For example, they can lock on to enemy targets on intertwined ground-engaging platforms, and use low-kill precision weapons to destroy them. Due to the smaller size of the UAV and the lower turning radius, it can even fly into tunnels or buildings to complete precise killing, which makes many tactics to deal with air strikes in the past ineffective, such as rapid ground advance and close combat with enemy ground forces , even if the air force has an absolute advantage, the other party will throw the mouse at the risk. This method becomes useless in the drone war and may even die faster.
  Another huge advantage of drones is less logistical support. In the past, to obtain air support on the battlefield required a large air base near the theater of operations, depending on the combat radius of the bomber or attack aircraft, and equipped with sufficient To protect against enemy attack, bases are undoubtedly important and vulnerable. Even a helicopter platform still needs the support of a forward base in combat, a solid base that can accommodate ammunition, parts and meet the pilot’s living needs, and of course, it needs to be equipped with enough security forces to deal with enemy attacks. However, the deployment of UAVs may be more dispersed and even mobile deployment, which not only reduces the logistical pressure, but also makes it very difficult for opponents to counterattack even if they want to. Although from the data point of view, the UAV is only a low-speed and small-sized aircraft, but its unique capabilities and positioning have fundamentally changed the battlefield situation, which is an issue that needs to be carefully studied and explored in the future.
