“Iran has enough people who can reach the heart of Europe and kidnap Americans and Israelis.”
Yeah, Iran does that and she's will get it.
But why Americans and Europeans too if the kidnappers are Israel's mossad?
Israel is the 'Little Satan' and America is the 'Big Satan', they see little difference.
I'd be far more likely to believe that Mossad did it than anyone else. And good for them, too. It would be kind of funny if an Iranian hit squad somewhere in Europe was found dead with their weapons and plans laid out for anyone to see.
