This was the perfect opportunity to act against Iran.
Regarding Reagan
It would have been a full-scale war
No public or congressional appetite existed post-Vietnam
The Soviet Union was strong
No support from the gulf states
The U.S. simply had no viable way of ending Iran
Reagan had to handle the USSR, which still was almost 10 years from collapsing.
GHWB had to work through the USSR's collapse and had to respond to Iraq's invasion of Kuwait.
Clinton started mini-wars in the Balkans and had interns to do.
GWB had the fall-out of 9/11.
OhBummer! started @#$% in Libya and Syria and had jetsetting to do.
Trump 1.0 was hobbled by the politics of the Trump-Russia-Collusion-Delusion, Shampeachment 1.0 and had to deal with Covid.
LIEden had ant-Trump lawfare to coordinate, bikini girls to watch at Rehoboth Beach, and tapioca pudding to eat.
Trump 2.0 had near-nuclear Iran to deal with, did and is, and is working to end the 47-year-old Iranian war on America.
Clinto, OhBummer!, and LIEden had geo-political space to deal with Iran, didn't, and the latter two shoveled billions of $$$$$ to Iran.
