We have not only abandoned democracies (many of which were more democratic than Ukraine), we have actually been the ones to destroy them. Mohammad Mossadegh in Iran, Operation Condor targeting every democracy in South America, genocide in Indonesia, etc, etc. Trump's stance on Ukraine is, at worst, not doing enough to protect a democracy from external threats, but America has frequently been the external threat democracies need protection from. Don't you see how that's worse?
