Abstract
The arrival of Donald Trump at the White House is commonly considered to have opened the way to a generalised assault on multilateral agreements and institutions, from the nuclear deal with Iran, the Paris Agreement on climate change, various trade accords, and restrictions on the use of land mines, to the United Nations, the World Trade Organization (WTO), and UNESCO. Given the impending US presidential election, the question that obviously arises is whether this pattern will continue or, instead, be reversed.
