President Joe Biden spoke in Poland on Tuesday, praising the democracies of the world for coming to Ukraine's defense against Russia's year-long invasion. This has sparked a divide among Republican 2024 presidential hopefuls over the US role in Ukraine, with some believing the Biden administration has done too much and others believing the US has not done enough. Biden alluded to his potential re-election bid in his speech, and the debate over the US role in Ukraine is likely to continue as the 2024 presidential race heats up.
