The Budapest Memorandum is a prime example of something I despise about Democrat foreign policy.

They meddle where they don't really belong and set up a place for failure with an agreement that doesn't obligate us to help prop up what we just broke with our meddling.

Get rid of your nukes and we'll support your cause at the UN was unnecessary.  But everyone was singing kum-by-yah at the time...

Ukraine, at the time, had a leadership that was friendly with Russia so the idea that Russia would ever invade seemed remote.

What great philosopher once said, "Never underestimate Joe's ability to fuck things up?"

It seems pretty clear that the Delaware Crime Family did some toppling of leaders in Kiev and that put some people who were  pretty hostile to Russia in power there.

And they got a war out of the deal.

The people responsible aren't punished.  Hell, they got pardons! 

Here's the important part, at least as far as the US is concerned:

The United States has no national interest in whom runs Ukraine.

Mr Biden had a personal interest in keeping the place aligned against Russia while he was president, but the United States didn't have one.

That's why we sent aid.

It's really cool that we got real world testing of some of our weapons, but that not enough of a return to keep doing it now that our president has no personal stake in the outcome.  It wasn't all smooth sailing with them either.

The current president, our ambassador, state department, etc., working with their counterparts in Ukraine, had hammered out an agreement to both create a national interest for us AND establish a trade balance that would allow the US to recoup the money spent.

All their president had to do was put on a fucking suit, smile for the cameras, enjoy lunch and sign the documents.

He chose, on camera, to be a petulant, entitled, demanding little prick just like he was two years ago when he was making demands of someone who wanted to help for personal financial reasons.

The American response to this kind of gratitude has always been, "have fun, fuck off."

Zelensky is the big problem for getting aid to Ukraine, he's been getting it despite himself because up until now the people he was dealing with had reasons to ignore the ingratitude.  

Those reasons are now gone.

PS: Lots of people said that giving up their nukes was stupid at the time, but everyone was riding the "end of history" wave and forgetting their Kipling.
