> You really can't see the parallels? An aggressive, unilateral land invasion of an Eastern European country?
By this standard, there's a new Hitler every year. George W. Bush was Hitler for invading Iraq. Obama was Hitler for bombing Libya. Clinton was Hitler for illegally bombing Yugoslavia. Of course, this is a silly way of seeing the world, and it will lead you to completely incorrect conclusions. Hitler, driven by an insane racial ideology and backed by conservatives who saw him as a tool to eradicate socialism, set about on an unprecedented expansionist policy that aimed at subjugating all of Europe, while carrying out a brutal policy of genocide almost without parallel in history. No, not every country that invades another country is comparable to that. In this particular circumstance, Russia is not waging a genocidal war, is not driven by a crazy ideology of racial superiority, and has no designs on conquering Europe. Russia has much more limited aims. Russia's invasion of Ukraine is criminal, but that doesn't make Russia the equivalent of WWII Germany.
> it is better for more countries to be liberal democracies than for fewer to be, and if Russia's invasion of Ukraine succeeds, fewer will be
In terms of corruption and lack of democratic freedoms, Ukraine is not obviously better than Russia. One thing this war is definitely not about is democracy.
