We have already obligated ourselves. The 2022 update shows they’re willing to pursue a nuclear path. I wouldn’t blame them. They’re in an existential fight, they trusted us and we sold them down the river.
Have you ever seen “Animal House”?
The Ukraine is Flounder.
Quite honestly, I don’t know why Ukraine agreed to the Memorandum back in 1994.
It was only within recent memory at that time that America had displayed its willingness to abandon an ally when the “going got tough” (see South Vietnam), or to turn on said ally when the power dynamics were different (see Saddam Hussein, who the US backed during the Iran-Iraq War, only to turn on him during the first Gulf War when the political winds had changed).
“Ukraine was coaxed to give up it nuclear weapons in exchange for a written pledge, should Ukraine ever be threatened or invaded, the United States would be there to intervene with military power.”
By signing the Budapest Memorandum, the USA did not agree to militarily defend Ukraine. That is simply not in the Memorandum and,
apart from this entry which is wrong, virtually nobody has contended otherwise. It is not a defense treaty and it never was.
