This has nothing to do with appeasement. The question is which countries are the most eminent enemies to Iran. Nobody is shouting "Death to Germany" or "Death to France" or "Death to Britain" there. Most Iranians feel close to those countries since there are close economical and cultural ties. I.e. Khomeini lived in Paris before the Revolution or the last President Kathami was several years in Hamburg/Germany. Western Europe is the window to the free world for the Iranian theocracy. Personally I am much more afraid of the Pakistani nukes concerning Europe in case of a change in power there.
Therefore it is obvious that a Iranian nuclear strike would be aimed to Israel or -if they really want to meet Allah soon- the US. If we would be ignorant (what we Europeans are not) we could say that this is simply none of our business. We try to be helpful with our (limited) means. Just take a look at my #40.
So just hope that the alligator eats you last? Nice that Germany has helped Israel. But this Iranian situation (and maybe the Pakis) cannot be "talked" to a resolution, do you think? Seems to me the talking is over....
