Remember this argument of yours when Mexico uses it to justify retaking California, New Mexico, Nevada, Utah, Colorado, Texas, and....wait for it...Georgia and Florida where recent evidence indicates that the Maya settled parts of Georgia and Florida long before the Spanish showed up.
Good point! Under Democrat leadership to open our borders, those jurisdictions may eventually themselves vote for succession and withdraw from the USA! Given that Democrats have disordered minds and cannot connect the dots, that is a likely outcome. Is this not happening already in Southern California?
As to the Ukraine, there seems to be no win-win solution. The EU is made up of mostly corrupt, socialist, and atheist countries. Who would want to join them? The Ukraine needs to settle its own internal affairs without any "outside" help.
You have to acknowledge that the Russians have a vested interest in the Crimean Peninsula port at Sevastopol. I know not the solution.
