I have to respectfully disagree.
That would be the perfect time to strike Iran ( since the world knows the US and Israel is going to do it any how ) because I don't think China would want to lose face or do any kind of disruption of their Olympics..... they would say out of it for that reason.
Most Gulf state countries have already told us privately ( go for it, we want you to strike Iran .. you have out blessing ).

The only reason I can see for waiting until they’re in the final stages of building a bomb is that’s when you have the maximum amount of fissible material and technical expertise, all in one place and at the same time.
