Ultimatum 2 is an action-packed, fast-moving saga. The American president is fed up with the hundreds of millions of dollars given to Russia to clean up high-level nuclear waste. His solution is to give the Russians an ultimatum: do this my way, or else! It is delivered in person by the secretary of state during a secret rendezvous in Norway.
A second ultimatum follows from the United States, Russia, and the United Kingdom to the government of Canada, after they decide that an international nuclear waste disposal site should be created in Canada. The Canadian prime minister tells their emissary there’s no way Canada will become a nuclear waste dump. The Americans threaten to invade. How the matter is resolved is ingenious.
