Ah the MUH CUBAAAA!!! argument. Even when the missiles came, they didn't fucking invade, hell they didn't even have the balls to support the exiles who DID invade a few years prior. And that was never the fucking question, the question was about would the US have the right to invade Mexico if they joined in a security agreement with China. The answer is fucking NO! All time time the same weak shit. And yeah, the Cuba fuck up had a lot to do with the US fucking up diplomacy in the area.
But none of that fucking matters because Ukraine doesn't have nukes, won't have nukes. AND FUCKING HAD NUKES and gave them up under the goddamed agreement that Russia wouldn't fucking invade them, and the US would have their back. They were dumbasses for doing that, like most countries were who signed Non proliferation treaties, or disarmed.
Putin had zero reason to believe that the Ukraine would attack or that NATO would fucking invade at any point. He has NATO members on his border already and THEY don't have fucking nukes or ICBMs either. Putin wanted an excuse, he has an excuse, and a bunch of idiots who want to jump on his dick just to be contrarian and feel smart.
