You have to suspect that if there were to be a nuclear strike on Germany it would not exactly please the rest of Europe, as they would likely get a lot of fallout too. You only have to look at the Chernobyl accident to see how far that stuff can go on the European jetstream, even with the prevailing Westerly wind that covers much of Europe a lot of the time, fallout still made it against that flow as far as Ireland, lots of it hit Wales too. So if France, Spain, the Baltic states and probably Russia too were getting a mouthful of radioactivity from a nuclear strike on Germany, it wouldn't much matter if there was some kind of mutual protection treaty from other nations or not, you could just bet one of the affected countries would be ready to pop over a few nukes if they had a clear idea of where any rogue nuke had originated from, and that's likely to be easy to trace since it lights up detection systems like a Christmas tree.
There have been precidents for considering this too, despite what many pacifists would like to believe following the two nukes that were used on Japan. Several countries were considering the use of them in Korea in the fifties, France has a nuclear deterrent independent of NATO, and Margaret Thatcher is widely known to have considered nuking Buenos Aires during the Falklands conflict; apparently the plan was to pop a Polaris missile over there from a sub (with no warhead on it), followed by a message saying something along the lines of,
'the next one will have a warhead on it if you don't feck off right now'. This was a contingency that was considered twice in fact, once before the fleet sailed and again as a back up plan if one of the two carriers would have been hit, as the makeshift aircraft carrier, Atlantic Conveyor was.
With that in mind, any terrorist would have to think very carefully about 'reaping the whirlwind', after all, despite the propensity of suicide bombers, they're not all suicidal, you don't see Osama, Ayatollahs or any of that crew lining up for the chance to strap some C4 to themselves do you? and that's supposed to be a guaranteed ticket to paradise if they really believe what they peddle.
If only they'd have chosen somewhere small with a crappy army as the Great Satan instead of the USA, they'd have probably won by now:rotfl:
