The US Civil War was not a foreign war, it was an insurrection, and in WW2 America was attacked and had war declared on it. WW1 and the Korean war are more debatable, but in WW1 Germany deliberately engaged in activities antagonistic to the US that they knew were going to lead to a declaration of war with unrestricted submarine warfare and the zimmerman telegram, they just hoped they would win before America could get involved. In Korea America was defending an ally that was facing an unprovoked full scale invasion and had full backing of the UN to intervene. I do agree that in Vietnam the US shouldn't have been sending conscripts though.
Three other things to add
1. The ww2/korea draft was continued by Eisenhower, and Nixon continued the Vietnam draft.
2. It was congress that established the draft laws, not the president. In 1918 the US Supreme Court in Arver v. US (a constitutional challenge to the WW1 draft, which argued amont other things conscription was a violation of the 13th amendment's ban on involuntary servitude) rightly explained that the constitution gives congress the power to declare war, and conscription to defend the republic has been understood as a duty of citizenship in times of war since at least as far back as ancient greece.
3. If you wouldn't at least have fought in the civil war or ww2 in whatever capacity you were able to if you had lived during those times, I have a white feather here with your name on it.
