Not sure what you mean, since this is nothing but a silly partisan shell game, but let's give it a try:
War of 1812: Madison, a "Republican" like Jefferson, who eventually renamed their party "democrat"
Mexican War: James K. Polk, Democrat
Civil War: Lincoln, Republican. Although I would point out that his it was his predecessor, James Buchanan, Democrat, that allowed the situation to deteriorate
Spanish American War: William Mckinley, Republican
WWI: Woodrow Wilson, Democrat
WWII: Franklin D. Roosevelt, Democrat
Korea: Harry Truman, Democrat
Vietnam... while tangled, Ike, Republican, refused to send more resources than arms. JFK, Democrat, sent advisors, LBJ, Democrat, ramped up the war with the introduction of troops, Nixon, Republican, oversaw the "Vietnamization" of the conflict, allowing troops to come home. And signed the peace treaty.
Panama, Gulf War: HW Bush
Afghanistan, Iraq: George W.
I respect our history too much to get into a "your side starts more wars" argument, but it looks like you just lost. And we can do the smaller incursions like the Barbary Wars, multiple incursions into Nicaragua, Haiti, Bosnia, Grenada, Lebanon, etc. And it breaks even.
Oh, and as to the video. He signed a contract. He has not been discharged, and is in the Individual Ready Reserve. If he had read his contract, he'd know that until he has his discharge in his hand, he isn't out of the military.
He can refuse all the orders he wants to. The UCMJ provides options to the military to handle those that don't fulfill their obligations, even if they are doing it to be cute pets of the left.
