Also Iran had been supplying Russia with a lot of parts for drones. Now they can't, making Ukraine's victory more likely than before.
The reasons for high oil prices now are a completely different cause.
but Trump also now has a excuse to abandon Ukraine,
and a excuse to lifte trade Embargos on Russian Oil (he already did)
this might still not change the outcome of the war, but might still be more useful then drone parts in the sense that if you either don't have money to buy drone parts or the seller stops selling you are better of with money?
and maybe he hopes for a Iranian terrorist attack before the midterms so that he can use that as an excuse to not have proper Election (Iran using terrorism for retaliation when other means fail isn't exactly new, so this isn't even that unlikely and a iff we assume he or the people consulting him really are that evil, then a false flag attack is also an option.)
