Why help Ukraine with billions and not other countries that do not have gas/oil?
Between donations from Ukraine oligarchs to Clinton foundation, Joe Biden's son involved in Ukraine gas corporations, the hundreds of millions spend by U.S. every year in Ukraine to "build democratic institutions", stories from recruited shooters planted in Euromaidan[2], here you are, saying U.S. officials are the good guys for the Ukrainian people. If that's not effective propaganda, I don't know what is.
And if you think the above situation is fine and dandy, I think there's nothing else we can say to increase our agreement. I'm not the kind of person who would interfere with my neighbours family, because their children didn't get lunch money for school, so that I can buy their house at a foreclosure auction later in the year when they divorce, but if you're fine with the U.S. government doing that kind of behaviour, then I should not interfere with that, either.

I doubt the US goverment is capable enough to finance and plan a coup of an not yet known goverment 20+ years in the future.
