Modern Republicans started the War In Iraq, War in Afghanistan and consistently push for war with Iran. Most major US Interventions that people dislike happened under Republican presidents, Panama, Grenada, Gulf War 1 & 2, Afghanistan, etc.. but most of these happened with Democratic support.
What I'm trying to say is, your gonna get bombed regardless, but with Republicans those bombs are more likely to be nukes. You should probably just turn off the TV and hope for the best rather than rooting for any side.
I think you should engage in better political analysis than saying that Republicans start more wars because Democrats are the ones who started WW2 and The Mexican-American war. I just don't really see the value in that. You should instead argue that modern wars, while usually started by Republicans, tended to have large political consensus on both the Democratic and Republican sides.
