"Democrat Party were always the pro-war party...".
So if you're saying Republicans didn't want to fight Hitler, Tojo, North Korean commies, and the Kaiser, then it is lucky indeed we had Democratic leadership willing to fight.
Hmm, let's see:
WWI - Wilson Dem
The world is better off that we defeated a militaristic and autocratic Germany, and that western liberal democracy was spared a German victory. French forces were on the verge of being overrun when we parachuted in
Before we even declared war, Germany committed to waging unrestricted submarine warfare against American shipping, and had tried to goad Mexico into attacking us.
FDR didn't start that war. Japan and Germany declared war on us first.
Since you're insinuating Republicans didn't want to fight Hitler and Tojo, we were fortunate indeed to have FDR at the helm.
The world is better off with a democratic South Korea, thanks to the vigorous American defense of our ally.
Since you are insinuating Republicans would have let North Korea commies take over the peninsula, it's fortunate Truman was willing to fight. Would you and Republicans also let commie China take over Taiwan??
Vietnam - Kennedy/Johnson Dems
The only one that was legitimately a strategic mistake, we should never have gotten involved in a civil war, and LBJ had to resign because democrats wouldn't support him for the 68 party nomination because of it.
