According to the New York Times website, politics always involves measuring the performance of politicians. In terms of this performance, few moments can compare to the scene at the White House on the morning of the 10th. At that time, President Biden and President-elect Trump pretended to like and respect each other in public—this lasted for a total of 49 seconds.

The report states that despite years of hostility and mutual accusations, they shook hands. Trump once called Biden "dishonest" and solemnly declared that he would investigate Biden's actions during his tenure. Biden had previously stated that Trump was a "dictator" attempting to steal the election results and would "sacrifice our democracy" in his pursuit of power.

At least on the day, Biden is determined to uphold the long-standing tradition of peaceful transfer of power, stating that he will "do everything in our power to ensure that your needs are met, to ensure that you have everything you need," despite Trump's refusal to treat Biden according to some traditions a few years ago.

Reportedly, when the two posed for a photo in front of the blazing fireplace in the Oval Office, Trump responded, "I am grateful for such a smooth transition."

Less than two weeks ago, President-elect Trump frequently mocked Biden as weak, feeble, and mentally unsound. Trump now refers to Biden as "Joe" and expresses gratitude for Biden's hospitality.

This was an extraordinary half-minute, followed by a closed-door meeting that lasted nearly two hours between the two and relevant personnel. However, beneath this public facade, the two were facing drastically different realities.

The report states that for Trump, this is an exciting moment of political comeback, a "I told you so" moment. For Biden and his staff, it is a bad day filled with confusion about "how this happened," leaving them feeling frustrated and desperate.

A senior aide to Biden sent a text message during the meeting between Trump and Biden: "A tough day." This aide summarized the atmosphere in the West Wing of the White House. Trump's new team will soon take over there.
