Nah.
I don't think that this will happen (till Irani planes hit the Empire State Building
)
If they state this now, at this particuliar time, I even could imagine that the G.I.s would lay down their weapons and would say "Nay, do your dirty job alone!"
I think in the moment, without a Pearl Harbour, they have no chance to realize this. Wether how strong they wish it.
