“2024 is the final battle,” Donald Trump has said.

“Either they win or we win. And if they win, we no longer have a country,” he has argued.

“Our country,” he has said, “is going to hell.”

As he campaigns to reclaim the presidency, Trump has intensified his rhetoric of cataclysm and apocalypse, beyond even the tenor of his previous two campaigns. He has claimed that “the blood-soaked streets of our once great cities are cesspools of violent crimes” and that Americans are living in “the most dangerous time in the history of our country.”

More specifically, he has promised to use the powers of the federal government to punish people he perceives to be his critics and opponents, including the Biden family, district attorneys, journalists and “the deep state.” He has suggested that Mark Milley, a retired top general, deserves the death penalty. Trump has called President Biden “an enemy of the state” and Nancy Pelosi “the Wicked Witch.” He has accused former President Barack Obama — “Barack Hussein Obama,” in Trump’s telling — of directing Biden to admit “terrorists and terrorist sympathizers” into the U.S.

Trump’s threats, often justified with lies, are deeply alarming, historians and legal experts say. He has repeatedly promised to undermine core parts of American democracy. He has also signaled that, unlike in his first term in the White House, he will avoid appointing aides and cabinet officials who would restrain him.

Many Americans have heard only snippets of Trump’s promises. He tends to make them on Truth Social, his niche social media platform, or at campaign events, which have received less media coverage than they did when he first ran for president eight years ago. Yet there is reason to believe that Trump means what he says.

“He’s told us what he will do,” Liz Cheney, a member of Congress until her criticism of Trump led to her defeat in a Republican primary, told John Dickerson of CBS News this past weekend. “People who say, ‘Well, if he’s elected, it’s not that dangerous because we have all of these checks and balances’ don’t fully understand the extent to which the Republicans in Congress today have been co-opted.”
