I don't think I agree. Can one call a nation that has been overtaken by a political coup sovereign? We backed the Egyptian coup, which we also helped to orchestrate and what have we there? We made all sorts of tactical mistakes in Ukraine. I do not want our guns and soldiers fighting for our foreign policy disasters no matter how badly I do not want to see Ukrainians part of a police state. But they voted for that corrupt govt in the first place.

I see your point about honoring agreements, but I have to disagree with you on this one. It is the honoring of agreements like this that lead to World War 1. We never should have agreed to be the protector for anyone. Oh, that we would once again take up the foreign policy espoused by John Quincy Adams:

America, in the assembly of nations, since her admission among them, has invariably, though often fruitlessly, held forth to them the hand of honest friendship, of equal freedom, of generous reciprocity. She has uniformly spoken among them, though often to heedless and often to disdainful ears, the language of equal liberty, equal justice, and equal rights. She has, in the lapse of nearly half a century, without a single exception, respected the independence of other nations, while asserting and maintaining her own. She has abstained from interference in the concerns of others, even when the conflict has been for principles to which she clings, as to the last vital drop that visits the heart. She has seen that probably for centuries to come, all the contests of that Aceldama, the European World, will be contests between inveterate power, and emerging right. Wherever the standard of freedom and independence has been or shall be unfurled, there will her heart, her benedictions and her prayers be. But she goes not abroad in search of monsters to destroy. She is the well-wisher to the freedom and independence of all. She is the champion and vindicator only of her own.

Does Crimea have the right to self determination?
