In other words..."If Iran had the ability to affect our nation, nobody would complain about the mess that we just created for the benefit of another nation."
It reminds me of when Sam Harris said that if Covid had been a deadlier virus, everyone would have thought that his take on lockdowns, masks and vaccines would have been correct.
Except COVID was not deadlier, and Iran does have the ability to affect our nation, thanks to its support of islamic terror.
