Yup.
No, you've been saying they should stop fighting.
It was a suggestion to both sides, not a command.
Uh, no. We didn't hear it in those cases. Those countries weren't invaded by another country that was clearly just trying to take them over. Stop trying to pretend this is the same as them.
Yes, and "this time, it's different" is also part of the same familiar pattern.
Russia invaded Ukraine for no good reason. Ukraine is fighting to maintain their freedom/country. We're helping them do that. That's not what happened in those other cases. This one has nothing to do with right-wing warmongers. In fact the right wing is in cahoots with Russia and is fully against giving more aid to Ukraine, which in itself destroys this your line of thinking here.
Our government has taken sides in a conflict between two opposing factions far away from us and where no U.S. territory is at risk. That's a similarity between this and those other situations I mentioned.
Another similarity is that it's typically presented as a "damsel in distress" situation where the U.S. is the white knight galloping in to save them from the evil dragon.
So, there are similarities here, even if you choose not to see them.
Oh, yes, and it's all about "freedom." It's always about freedom. That's our job, as the leader of the free world. We've heard that on all those other occasions, too, so there's another similarity.
Each time also carried the implied threat that, "if we don't stop them and/or stand up to them here, they'll just keep going and going and going." The Domino Theory in Vietnam seemed to carry a lot of weight among US policymakers, who believed that if the Communists weren't stopped in Vietnam, all the other Southeast Asian states would tumble like dominoes. Nicaragua and US aid to the Contras carried the same message. The view was that, if we didn't stand up to the Sandinistas, communism would spread throughout Central America, and into Mexico, and into the United States. It was the same with the invasion of Grenada.
I'm not pretending that they're the same. I'm not even saying that they are the same. All I'm saying is that, what I'm currently hearing about Ukraine is a familiar refrain from what I've heard in the past about other crises. Ordinarily, it's been a position echoed by those who generally advocate a more militaristic and interventionist set of foreign policies, most of whom tended to reside on the right side of the spectrum. I can't explain some of the more recent anomalies you allude to, regarding the right-wing and left-wing today. Politics have gotten rather weird lately.
