I can support whatever I want. However, you as a Democrat must follow your alliances. If you are against Putin, you have to be against all his allies. By your logic, Bulgaria has to give their land back to Turkey as they occupied us for 500 years. I think issues like that are too complicated for a mew worlder like you. Oh, I see now. You defend the occupiers because if not, the US has to return the land to the Native Americans.
That is a silly argument.
Of course all land can't go back, but I reckon we can have a reasonable cut off point, at least 50's or 60's. Otherwise it is wide open and putin is right, yours is what you can take.
And no, I don't have to follow alliances against morals and law. Biden is dead wrong on this one.
