if there's a will, there's a way... that is for the US.
If Israel won't be able to convince Iran to stop obtaining nuclear weapons, US will surely find a way to attack Iran. US is very good in fnding waya to come up with a stories to justify the need for war. I hope they don't come up with another 911. US benefits from wars. Evertime they win, that's money flowing to the US and in this case, it will give US control of OIL since Iraq has been neutralized already.
Maybe they won't attack.. and maybe they will. Bottom line... I believe that Iran is their next target.
