This is an exaggeration. The larger European military powers spent enough on defence to be able to operate without US assistance in a range of circumstances (e.g. the Falklands war). But Europe did not anticipate having to defend itself against Soviet aggression without US assistance.
In fairness, it would have seemed crazy, not so long ago, to think that the POTUS would be on friendlier terms with the leader of a Russian dictatorship than with the democratically elected leaders of France and Germany. But here we are.
