It's not a complete US success, but what the OP said was a huge understatement. Iran situation had gotten much worse during this war.
Regarding NATO, this is a European effort of undermining the alliance no more than it is the US.
Europe is rightfully saying that Ukraine is our, the entire western world, war.
However, when the US bombs the very factories that manufacture these drones used in Ukraine, and the nation that quite frequently kidnaps european citizens as political chips, the europeans say "this is not our war".
