Yes, and when Mexicans are a majority of Texas, maybe we should just let Mexico march in and take it, just like the thug Putin and his army of savages did to S. Ossetia.
Self-Determination is only one part of the equation when it comes to territorial changes like this. Texas voted and decided to become part of the Union after being it’s own country and S. Ossetia has done the same. S. Ossetia was forced to become part of the Georgian SSR during the communist regime and promptly left Georgia when the USSR dissolved.
If you want to make an analogy then imagine the US Federal Government disolving, if such a situiation were to occur then Texas would be right in deciding it’s own fate, whatever that might be.
As the Declaration says, “Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes.” So there is no justification for Texas to leave now nor should we allow it to do so even if Mexicans are the majority.
But when the USSR fell apart; Georgia, the Ukraine, the Baltics, and a dozen other regions decided to leave Russia. As much as a right as they had to leave, so did others have a right to stay. Since independence, Georgia has not controlled S. Ossetia and the only reason that I see that Georgia has a claim on the region is that the SOVIETS forced them to be a single SSR. And what justification is that???
