Just what does he owe Ukraine for? What favor did they do for him that he’s repaying?
I don’t think the thinking goes in that direction nor along those lines.
The thinking is, “Here’s a chance to dump a towering s**tload of money into an unaccountable black hole under cover of doing a righteous deed, that of helping the Ukes fend off the evil Russian bear and the Ukes will ultimately lose anyway and we’ll get to do it more and more. We’ll look like heroes and siphon off millions.”
And I’d go farther:
“we had better get in on the grift during this war/destruction phase because we don’t know how long it will last.”
Closely followed by: “And then we’ll be there to provide rebuilding aid when this phase is over.” You can bet your bottom dollar these plans are already being drawn up, the covering propaganda prepared in advance.
The idea is to stand next to the waterfall with your spoon out. The bigger the waterfall, the bigger your spoon, the better. Get next to the biggest money flow you can with biggest spoon you can. That’s all this is. The number of lives lost, the extent of the destruction is low level collateral damage.
