"This seems to imply that the pursuit of war is a preference in non-Democrats."


No. It merely faces the reality that the Democratic Party has, since the Viet Nam conflict, been the home of the anti-war group.

Some may see how that makes the Republican party a better option for realists who understand that war may, in times of National defense, become necessary. You may think that never to be so. I bet you wouldn't be elected from either party.
