...Civil War, World War I, World War II, Korean War, Vietnam War.
All these wars started under Democrat Presidents.
1. The democrats were southern conservatives during the civil war. The parties switched during the civil rights period in the 50's and 60's with the liberal pro-rights republicans joining the democrats and the conservative southerns joining the republican party. Must be nice to not understand history as you most certainly do.
2. WWI would of happened no matter what the United states did. Lol! Pick up a book.
3. WWII would have happened no matter what the United states did. lol! Pick up a book!
Would the outcome of those wars have been different without the united states? Maybe! Hitler may have won without us arming Stalins USSR to the teeth. Stalin threw 20 million troops at the eastern front and our armor helped keep Hitler off of Britain back. The european front was going to happen no matter. The japan front, well, do you wish FDR would have want over to Japan and sucked the emperors dick?
Korean war? Maybe you have a point...Fighting communism and all that was also a republican thing.
Vietnam...I'll give you some points hear as Kennedy and LBJ did play a huge roll in getting us into this war. Again are you anti-communist or not? Nixon also kept us in this war for another ~5 years.
What would the republicans have done if Nixon would have won instead of Kennedy in 1960? That is a interesting one. I'd think Nixon might have done very little different considering he was also anti-communist.
