The legacy of Democrat foreign/military policy

Truman:

Cold war (containment policy) = win
Korea = draw

Kennedy:
Bay of Pigs = disaster
Cuban Missile Crisis = The last Democrat backbone sighting in human history
Vietnam escalation = disaster

Johnson:
Vietnam escalation = disaster

Carter:
Iran hostage crisis = An Iranian Act of War is responded to with Carter-era malaise and fecklessness
Israel-Palestinian Accord = enabled the Intifada

Clinton:
Bosnia war = modest success
Somalia = Black Hawk Down
Dayton Agreement = Enabled the thug Arafat to maintain power

Let’s now look at significant foreign policy initiatives of Republicans:
Eisenhower:
Gary Powers incident = oops! No harm done, really. Soviets drained significant resources into their anti-aircraft systems afterward.
Cold War = executed the policy

Nixon:
Vietnamization = Cleaning up the mess Democrat foreign/military policies made
China = Imagine the world had he not gone?

Reagan:
Iranian Hostage Crisis = Coincidence they were released the same day as Reagan took office?
Cold War = Ended it by out-spending the Russians and proposing “Star Wars.”
Grenada = Snuffed out an attempt to create a Mini-Me Cuba

George H.W. Bush:
Kuwait-Iraq War = Possibly the greatest military victory in human history
Panama = Regime change completed, Drug-lord Noriega overthrown.

George W. Bush:
Iraq Liberation = Ultimate outcome still in doubt. People with the same anti-war mindset who were responsible for the failure to win in Vietnam are reprising their role here (which is about the only parallel between the two situations, actually.)

I’m not saying that Republican achievements in foreign/military policy are uniformly successful, but can someone tell me why anything Democrat leaders say regarding foreign/military policy has any credibility at all?
