Historical analysis shows a shift over time: while Democrats were associated with major 20th-century wars like World War I, World War II, Korea, and Vietnam,
since the 1990s, Republicans have been more frequently linked to launching new conflicts. For example, George H.W. Bush started the Gulf War, and George W. Bush initiated the post-9/11 wars in Afghanistan and Iraq. In contrast, Democratic presidents like Clinton and Obama engaged in military actions (e.g., Kosovo, Libya, drone campaigns) but often without large-scale ground invasions.
