Okay, so where are the US forces, to reinstate the Ukrainian border? The border is no longer integer.
US security guarantees are not worth the paper they are written on.
Russia sends in tanks. USA sends a tweet.
Discussion
Russia and the USA agreed to continue to respect the Budapest Memorandum, which has as its first clause:
> Respect the signatory's independence and sovereignty in the existing borders
We’ve given them almost 190 billion dollars…
No, actually, you haven't. Most of that money was spent in the USA or by the US military in Europe. 20% was loans, not grants. Some it was promised, but not yet sent, as it can take years for contracts to clear. They've received more like $75 billion, directly to the Ukraine government.
Anything "associated with Ukraine" gets paid from that budget line item, but the Ukrainian government never sees most of it. But they _have_ received weapons and recon, which have been game-changers, so they don't usually complain.
It works like this:
Congress agrees to $50 billion in "military aid to Ukraine". The US Defense Department spends the money on developing a new weapons system, training troops on that system, producing the system, delivering the system to its arsenals. It makes room for that system by removing the older stuff, that was scheduled for decommision. It sends the older stuff to Ukraine.
The older stuff, that it would have had to pay to dispose of, gets sent to Ukraine. Same thing Germany did. Sent them everything they wanted to get rid of.
Another thing the US does, is that it loans Ukraine money, on the condition that Ukraine spend that money buying American arms. (EU does the same thing.) So, it's a defense industry stimulus package. That's why these "presents to Ukraine" often get approved by people who don't like Ukraine: the money actually goes to Americans, not Ukrainians.
The USA has probably made money off of "helping Ukraine", in fact, as everyone can see that the US-made stuff is vastly superior to the Russian-made stuff, and now they're completely swamped with weapons orders for high-grade stuff that goes for like $80 million a pop.
