Also WW's Sr. and Junior, if you care to extend the pattern back, though those both began and ended under Democratic administrations. In the case of the latter, the Republican general leading the war effort became the next US President --- which suggests that there's some haziness to the attributions being made. That same administration participated in violent campaigns in Iran (overthrowing democratically-elected Mossedegh) and Guatemala, as well as planning the Bay of Pigs operation (which occurred as Kennedy's administration opened).
Antiwar sentiments existed for many of these, though it's notable that considerable anti-war sentiment in the US against entry into WWII had a distinctly hard-right flavour to it. Not all anti-war sentiment, as there can be many possible motiviations, but in this specific case, domestic groups sympathetic with (and often orchestrated by) rightest European belligerents had an outsized role.
The anti-war movement of the 1960s and 1970s became associated with Democrats as that party swung leftward and shed its own long-standing Southern affiliations, and grew our of anti-nuclear and civil rights movements of the 1950s and 1960s, all of which saw Vietnam specifically as an unjustified and unjust war, with considerable merits to that viewpoint.
Painting pro- or anti-war sentiments as distinctly left or right, or aligned with either of the two present major parties is not historically accurate and misses considerable nuance.
