There are million of people who trusted US and Europe to help them remove the boot of communism from their throat. The "agreement" is made and those people, relatively helpless by design, are poised to re-enter the nightmare they were fortunate to get away from.

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.

in 1994 Ukraine dismantled its nuclear capability and scaled back it military on the condition that external powers would protect it in the event that Soviet (communist) expansion was to rear its ugly head again. Similar agreements were made with other former block nations where the US was supposed to place missile defense shields. O first took away the promise of missile defense shields and now he's allowing the Russians to walk into a sovereign nation and take land under the threat of force? Why should we care? We gave our word to a freedom seeking people to be there for them if/when the shit hits the fan.

Paul is wrong.
