Hold on. We have people in S. Texas and S. California who don’t want to be in the country. Worth “p*ssing away the lives” of Americans over?
Civil Wars rarely result in outright victories. The American Civil War is the exception.
Ukraine - Western Ukraine, is simply outmatched and outgunned by the more populous east, which enjoys the support of Russia. It never stood a chance of regaining control over the entire country.
People are going to demand the army cut its losses and pull out of the Donbass. Those same West Ukie soldiers who won’t bleed there will defend their home turf.
Which Putin won’t take.
