But probably itching to do to the US what the US did to them in Ukraine.
(And doing so is likely to reduce US aid to Ukraine, as a bonus to them. Ukraine's certainly not likely to get Tomahawks and Patriots right now.)

I said "did to", not "is currently doing to".
And what better way to support that by making some money selling weapons, especially if it gives you a chance to expand your manufacturing base due to increased demand?
