Disagree.
1) Failed regime change: Even after the U.S. blew up Iran's high command and killed Khamenei, the government didn't cave. Instead, an even more hardline leader who lost his dad, wife and daughter, from these airstrikes, took over.
2) Nuclear program and Uranium stockpile still intact: The main reason the U.S. started this whole thing was to destroy Iran's nuclear program. Yet despite everything that was thrown at Iran, the uranium is buried too deep underground, and now Iran has a massive excuse to actually build to protect their program and stockpile.
3) Proxies Network: Sure, the U.S. had quite a lot of successful operations smashing their equipments. But groups like Hezbollah, Iraqi militias, and the Houthis are still there. Hezbollah is still hurting Israel even as we discuss here.
4) Strait of Hormuz: Iran choked it so bad that it is affecting the world's economy. If US was so confident about reopening it, they would have at least taken one of the islands. Yet they couldn't and they are literally stuck there. Oh and thjsenergy crisis is worse than the 1970s and 2022 combined. Not exactly a stalemate here when this operation is a double edge sword when your own oil and gas prices skyrocket so badly that you are now hated even more in America.
5) Ammunition Depletion: burned through so many expensive ammunitions that USA may not even be able to have enough defence weapons to protect yourself in the next war with Iran, let alone defend other areas against China or Russia. Strategic victory for Iran in the next war while it still uses cheap drones and ballistic missiles which is still intact among its underground bases.
6) Alienated Allies: Trump basically jumped into this without telling its allies, and then got mad when they didn't want to help. The economic damage and mess have left America looking bad on the global stage.
I don't see how this is even a strategic victory for US let alone marginally winning this war. This war is not over yet, but mind you Iran have practically won round 2. I would even say the scale is balance if they can achieve back 2 out of the 6 here to pre-war status.
