Uhmm, no. The “west” could outlaw Iran forever and begin bombing in five minutes ;).
The only problem is that few western states want to go “all in”. If you want to solve the problem you have to start a full-scale invasion - for which Israel is to small anyway. If you just take out the nuclear sites, you keep Iran from getting the bomb, but at the same time keep the regime in power for another 20 years or so. What the west would really prefer is if the Iranian people just took care of the fascists in power themselves.
Now that would be (regime) change we can believe in.
big difference between “can’t” and ‘won’t”...
If this is true the Western Powers would do more to help the
Iranian opposition.
