Conservative Washington Post columnist George Will released a startling video claiming that President Donald Trump has reduced the power of the American presidency, and in turn, changed the global order.

“The president has been, presumptively, the most powerful man in the world for so long that Americans might be startled to know that it’s not written in the laws on nature,” Will said in the video.

“Trump has pulled America back from the alliances which made the president so powerful,” he explained, before highlighting the president's seeming ignorance on trade policy and international relationships.

“The confidence that other nations have in the stability and steadiness of American leadership is diminished when the United States goes through arduous lengths to negotiate something like the Trans-Pacific Partnership and then, almost on a whim says, never mind," he explained.

Will concluded that contemporary economic and geopolitical realities under Trump have elevated another leader to the status of "most powerful man in the world"—Chinese President Xi Jinping.

The assessment is especially troubling in light of Xi's recent successful play to abolish term limits, allowing him to theoretically stay in power in China for the rest of his life.
