The United Nations and other international organizations are bracing for four more years of Donald Trump, who famously tweeted before becoming president the first time that the 193-member U.N. was "just a club for people to get together, talk and have a good time."

In his first term, Trump suspended funding for the U.N. health and family planning agencies, withdrew from its cultural organization and top human rights body, and jacked up tariffs on China and even longtime U.S. allies by flaunting the World Trade Organization's rulebook. The United States is the biggest single donor to the United Nations, paying 22% of its regular budget.
