But he delivered on other fronts. He immediately enacted a federal hiring freeze, as he had promised, and mandated that for every new federal regulation enacted, two be eliminated. He launched an aggressive campaign to roll back environmental protections passed by the Obama administration, including those that protected waterways, encouraged cleaner energy, reduced auto emissions and restricted offshore drilling and oil exploration on federal land. At the same time, he has prioritized tapping the country's shale oil, and natural gas and coal reserves.
However, courts are undoing many of Trump's environmental rollbacks, calling them poorly reasoned and illegal.
On trade, Trump renegotiated the North American Free Trade Agreement and withdrew the U.S. from the Trans-Pacific Partnership, but failed to decrease the U.S.-China trade imbalance while starting a trade war with the country.
On the international front, the impact has been enormous as he has put his "America First" policy into practice, fundamentally redefining America's place in the world. He increased funding for the military, joined the race to weaponize space, all but abandoned efforts to curb nuclear proliferation, and has threatened U.S. membership in the landmark alliances of the 20th century, including NATO.
At the same time, he has pulled the U.S. from participation in a host of landmark accords, including the Paris Climate Agreement and the Iran nuclear deal (though he failed to bring Iran back to the negotiating table to broker a replacement deal, as he had pledged.) At international summits, he has cozied up to authoritarian leaders, including Russia's Vladimir Putin, while picking fights with longstanding allies like the U.K. and Canada.
In a sign of just how far he has broken from the global community, he stopped funding the World Health Organization in the midst of the pandemic earlier this year.
Jeremy Shapiro, a nonresident senior fellow at the Brookings Institution, said Trump has altered U.S. foreign policy in ways that go beyond what he outlined before taking office.
"I don't think he was really preparing people for the degree of revolution. He didn't say, 'I don't care about human rights' on the campaign trail. He didn't say, 'I don't care about democracy.' He didn't say, 'I don't care about alliances,'" Shapiro said.
While Trump complained the U.S. had gotten a raw deal in so many areas, he has failed, Shapiro argued, to negotiate improvements, aside from perhaps the new NAFTA.
"It's easy to destroy a deal. It's much harder to create a better one. And he hasn't done that," Shapiro said.
