An explosion at the top of the world - a crisis is closer than we think.

Richard Rohmer’s Ultimatum is the story of the U.S. invading Canada as written by a Canadian. More precisely, it is the buildup to the invasion, the haggling, set in the backdrop of the 1970s energy crisis as the embargo-facing US confronts resource-rich Canada.

I really enjoyed Ultimatum and the sequel Exxoneration. I read it many years ago, but I think about it regularly which, I think, is a good sign of the impact of a book. It's one of the closest things to patriotism in Canadians I've ever read.

Pulpy, fun, and provocative. Essential Canadian alternate history.

“Now I want you to prepare for a briefing…!”

Like super-charged dominos, one fantastic meeting leads to another when the President of the United States calls the Prime Minister of Canada and delivers the ultimate ultimatum: Give us control of your oil… or else! Prime Minister Robert Porter’s schedule rapidly fills, and he also takes a number of phone calls, while the President personally pilots Air Force One to the brink of war… and the shores of Hudson Bay, to inspect some pipe. While the clock ticks down, a nation debates “not so much the access to the energy reserves of the Canadian Arctic as the whole question of an independent future for Canadians.” Sam Allen, Inuit terrorist and the Prime Minister’s best friend, must make an terrible choice between two loyalties, and when tragedy strikes, the leader of a proud land declares: “That was a brave, brave man. I must phone his wife. I knew them when I was in Inuvik.”

Time’s up. Will it be war or not war?

I first read this in 1973 or 74. At the time, I thought it "pulpy" as another Goodreads reviewer put it, but not bad. It was believable, but unlikely.

The US decides it needs Canada's Natural Gas reserves, and will go to any lengths to get them. Canada says "you just can't take them, but we'll cut you a really good deal (even after you screw up so badly that anyone else would say you'd blown your last chance), because we're Nice People."

Now, reading it more critically, I think the writing is perhaps better and unfortunately the story (replace Gas with Water) is getting more believable by the minute.

Canada is not the 51st state, and Wayne Gretzky and Elon Musk have both committed treason.

Written in 1972, a somewhat obscure and very interesting read, particularly in light of President Donald Trump's statements in 2025 of Canada becoming the 51st state of the USA. a little slow in parts, but the inevitable ending will probably apall you.
