Re: Spot.The.Pattern.:
One of those is very unlike the others.
I'm talking about DeGaulle's withdrawal from the military part of NATO. They annoyed a lot of people (and this was when memories of kids who'd gone to France to fight the Nazis - and didn't come home - were fresh), but nobody sent tanks in to stop them. For that matter NATO bases were all moved off French soil - including the HQ which went to Belgium.
