While Ukraine is up against a pretty brutal invasion from a Russian dictator, the “great” state of Texas has some parallel elements with the ongoing struggle between the two Slavic nation states.
Firstly, the Texas War for Independence was similar to the the Crimean “uprisings” Ukraine experienced around 2014. While they had alleged separatists wanting to rejoin Russia, the Texas movement was fueled by numerous American settlers who wanted to break from Mexico and indirectly join the US. Sure there’s differences. Millions of Russians who reside in Eastern Ukraine were voluntold to relocate there during the Soviet regime. Partly due to Stalin’s genocidal policies with the Ukrainians (now the SCLM is mentioning the intentional famine in the Thirties) which suddenly created openings and the rest just being the nature of the USSR. It was a giant state so mobility was “easier” and Russians often got the better gigs regardless of the region’s ethnic majority. With Texas, Mexico had a hard time getting its citizens to live there and defeating the First Nations already present. They lured the Anglos to do the dying and killing in exchange for land. Mexico figured it was a win-win scenario. I’m guessing, they’d step up their presence once Texas was more secure.
What would follow later is how the two conflicts line up more. Putin made up a load of bullshit to invade his Western neighbor. There may have been some Nazi sympathizers present, yet its doubtful any government in Ukraine over its recent 30-year run are fans. As for Texas, the people running the Republic knew they were on borrowed time. There was no way they’d survive without American intervention because Mexico would lick its wounds, regroup and retake the land in a matter of a decade. Ergo, President Polk and his cronies made up some crap to justify a war that ended in US forces storming Mexico City.
Throw in America’s History of ignoring other place’s sovereignty: Iraq, Nicaragua, the Philippines, Cuba, the Dominican Republic, Panama, Guatemala, Iran, the First Nations, etc. It sadly gives Putin, Xi and the dictator’s club some cover to tell the UN and the US to go screw itself since “do as I say, not as I do,” is hard to enforce.
