The Muzzies killed 241 US Marines, sailors and soldiers in 1983. I do not remember Pres. Reagan exacting any horrific vengeance on the perpetrators. Ronald Reagan was the second finest POTUS of my lifetime,, ( Ike is first), but he had his failures. So I don’t expect a non sentient zombie in aviator glasses to do something Reagan didn’t.
I think Reagan realized that his mistake was getting involved in Lebanon in the first place.
If he wanted revenge, it could mean the deaths of 10,000 G.I. Joes.
