Honor Our Commitments?

The Ukraine made the mistake of giving up the nuclear arsenal that was left behind when the Soviet Union collapsed in exchange for security commitments, including a treaty signed with the United States. The Ukrainians should not have believed America because we do not have a record of keeping our promises. The Federal government signed treaty after treaty with American Indian tribes, only to ignore or break the treaties when abiding by them became inconvenient. Ask South Vietnam what America's signatures and pledges mean. Oh, sorry you can not because it was conquered and absorbed by North Vietnam, so now there is just Vietnam because the US broke our promises. Security assurances made by previous American administrations mean little. Obama's pledges about protecting other nations mean absolutely nothing.
