Geography has given the US unrivaled security. Trump is destroying it

The US’s greatest strategic advantage is its friendly neighbors. But its ties to Canada and Mexico are being undermined

The secret to American power and pre-eminence was best summed up more than a century ago.

America, observed Jean Jules Jusserand, France’s ambassador to the United States during the first world war, “is blessed among the nations”. To the north and south were friendly and militarily weak neighbors; “on the east, fish, and the west, fish”. The United States was and is both a continental power and, in strategic terms, an island – with all the security those gifts of geography provide. No world power has ever been as fortunate. This unique physical security is the real American exceptionalism.

Americans take this providential geography for granted: their country’s wars are always away games, and their neighbors are trading partners and weekend getaway destinations, not rivals or enemies. The ability of the United States to project power around the globe depends on technology and logistics, but it rests ultimately on the foundation of secure borders and friendly neighbors. But that may not be the case much longer. In threatening war with both Canada and Mexico, Donald Trump is obliterating America’s greatest strategic advantage.

In normal times, one would be hard-pressed to find a pair of friendlier nations than the United States and Canada. Canadians and Americans share a common language (aside from the Québécois), sports leagues, $683bn in trade, and the world’s longest undefended border, more than 5,000 miles (8,000km) long. Americans and Canadians have fought side by side in both world wars, as well as in Korea and Afghanistan.

Trump’s coveting of Canada is easy to mock and dismiss. Since returning to office in January, he has said repeatedly that he wants to make Canada the 51st state and taken to calling former Canadian prime minister Justin Trudeau “Governor Trudeau.” In what could be a satire of the post-9/11 ambitions of some American neoconservatives, Trump called the border with Canada “an artificial line” that “makes no sense”.
