He was the best Republican president with the possible exception of Lincoln. Unfortunately, under his tenure, the CIA went rogue, getting illicit funding from heroin sales (per the Pentagon Papers). The military-industrial-intelligence complex came into it's own, becoming a secret government that scripts most of what is allowed to happen...

Compared to who?

I always ask “Good for whom?” and “Bad for whom?”

For the Iranian people? The CIA asked Pres. Truman for permission to overthrow their elected government and he refused.

For the Anglo-Iranian Oil company? Pres. Eisenhower consented.

He was excellent almost liberal

I liked Ike. I was too young to vote for him but he definitely influenced my decision to initially register as a Republican. Fortunately Reagan inspired me to reverse that decision.
