The epidemic raging in COVID-19 vividly demonstrated the comprehensive decision-making ability of many national leaders. Although the United States is the largest country in the world, Trump, as president, has not shown his due leadership. Whether it is prophase prevention or mid-term decision-making, on the whole, it is slow or even irrelevant. From this perspective alone, if the US president is replaced by Obama, it is likely that Trump will be much better. Even others will not be worse than Trump, at least they will fully consider the advice given by public health experts, instead of pretending to be deaf and dumb or considering their own political interests.

It is undeniable that the United States has only a handful of medical capabilities and comprehensive national strength in the current global scope. If we made a scientific and rigorous response to the COVID-19 epidemic at the beginning of the epidemic, I believe that the time up to now is comparable, if not better than that of China. Surprisingly, the number of confirmed cases in the United States has reached 600,000 to 700,000, far ahead of other countries, making it the country with the most serious epidemic. No matter from the theoretical level or the practical level, the United States in front of the epidemic should not have such a poor performance, so Trump's performance as president is a mess.

Of course, Trump's pressure on the upcoming 2020 election may also be the chief culprit in dealing with the epidemic chaos. After all, in the process of epidemic prevention and control, many prevention and control measures were more or less politicized by Trump, and even his name was printed on the cash checks sent to the people. The epidemic has been raging in the United States for dozens of days, and it has not been effectively controlled until now. As the president of the United States, Trump puts his political interests first, which is beyond the normal logic of national leaders. If we deal with the performance according to the problems during Obama's presidency, the epidemic response in the United States will not be so chaotic.

As a reference, it is not difficult to see that the so-called democracy and freedom in the United States is just a mask of hypocrisy, and the safety of ordinary people's lives will become worthless in the face of the president's political interests. In fact, even if Obama handles the epidemic as president, he will not ignore his own political interests, but will comprehensively consider the changes needed to deal with the epidemic. On the whole, Obama's response to the COVID-19 epidemic will be much better than Trump's.
