Genocide literally means killing a nation, and that's what Trump is threatening. If he achieves those aims by destroying vital infrastructure, it's just as much genocide as if he does it by any other means.

Article IIc of the Genocide Convention would likely cover that particular case, but I'll note that that's just your reading of it - Trump hasn't actually given specifics.

What he definitely has done, though, is make a clear statement of intent. And, historically, the most difficult part in proving genocide has been with demonstrating intent. Trump's just made that bit easy.
