Similarities with what?
The Spanish civil war was international communists v. World.
The NAZI’s were NAZI”s, but that doesn’t mean they were wrong about EVERYTHING.
They gave the world working turboJet and Rockets, the swept wing, our interstate highway system, so they were pretty sharp people, and could see the threat of international communism.
The Democrat party thinks if we all vote for international communism, it’s “democratic”(because they are too dumb to realize it’s the last vote they’ll ever make). The NAZI’s were smarter than 1/2 the US population.
US giving arms to Ukraine, is like us giving support to the UK in 1940/41. We would have done the same for France if they weren’t gun droppers.
I think you trying to oversimplify a complex war. Communists were evil, but Franco was no angel. And the Ukraine conflict is not the same as England 1940. The US is manipulating Ukraine, but at this point the US can't easily free itself from the tar baby, and maybe doing would be dangerous at this point. Democrats, aided by the GOP, are the new warmongers.
