Off course they all want to destroy Iran's nuclear facilities!- but the issue and million dollar question is HOW DO THEY DO IT? Because they just can't do it anymore, whether logistically, financially, politically, ideologically, militarily, religiously, i mean, its too much risk and work and difficulties for even US to attempt (in over 3-4 decades and counting)- and US is in the best position to execute an attack on Iran- US can do it actually, but its deterred from doing it because it has figured the risk and cost outweigh the chances of "success". Iran's airspace is dangerous for adversaries, that is the truth- if its false, then why hasn't US or Israel staged a strike yet? a good % of their jets wont make it back out of Iran after bombing sites there.
