The treaty forced the US and Russia (then the Soviet Union) to eliminate ground-launched ballistic and cruise missiles with ranges of about 300 to 3,400 miles. In 2014, the US accused Russia of violating the treaty in 2008. The Trump administration believes the treaty puts the US at a strategic disadvantage with China.

A massive climate pact that includes nearly every country in the world, the Obama administration signed the US on, promising to curb its use of fossil fuels and to help mute the effects of climate change. Trump said the deal was poorly negotiated.

A massive trade deal meant to counteract China's economic power. Trump ran on a promise to spike the plan, saying it was unfair to American workers. The pact was never officially adopted by Congress. The other 11 nations have carried on without the US.

Trump renegotiated the deal to cut down on a trade deficit with South Korea. The Koreans put limits on the amount of steel they would sell to the US and the US exempted South Korea from the steel tariffs Trump imposed on many other countries.

Trump repeatedly complained that the Clinton-era North American Free Trade Agreement, which remade the US economy, was poorly negotiated and gave too much away to Canada and Mexico. Its renegotiation, which he achieved this year, is less a wholesale rewrite than an update for the 21st century, albeit with help for dairy farmers in Wisconsin. Also, it got a new name: United States-Mexico-Canada Agreement (USMCA).

The group of industrialized democracies, created in the 1970s, notably ejected Russia over its forcible annexation of Crimea in 2014. That's an episode less troubling to Trump, who wants Russia back in the room to make it the G8 again.

Trump has not only ended agreements or questioned them. He also made history by working directly with North Korea. The deal he entered has led to a North Korea pledge to halt its nuclear program, but the specifics are complicated.

US Ambassador to the UN Nikki Haley accused the 47-member body of bias against Israel and a failure to hold human rights abusers accountable. The US pulled out of the group the day after the Office of the UN High Commissioner for Human Rights slammed the separation of children from their parents at the US-Mexico border as "unconscionable." The rotating 47-member body represents a larger group of 107 nations.

The US stopped paying dues to the international body in late 2011 after the agency voted to accept a Palestinian bid for full membership and now owes approximately $550 million. The State Department cited an anti-Israel bias in pulling out of UNESCO in 2017. The US also had withdrawn from 1984 until 2002.

Trump campaigned on a promise to withdraw the US from the Iran nuclear deal engineered by the Obama administration and others in the world community, and he delivered in May, despite an onslaught of lobbying from European leaders. He said the deal, in which Iran promised to ice its nuclear program in exchange for eased sanctions, was flawed. He promised to negotiate better deals and pointed to North Korea.

Trump has teased upending the North Atlantic Treaty Organization, which was created to counterbalance the Soviet Union and is one of the oldest and most important alliances the US takes part in. He's long complained that smaller nations don't spend the same proportion of their GDP on defense.

Trump has been frustrated by international trade rules the US accepts as a member and his administration has written a draft bill, not yet introduced, that would seek to abandon key WTO principles on trade. He's hated having to get approval from Congress and instead focused on things like tariffs he can do on his own.
