That's the thing, winning depends on your goals.
Iran's goal was to survive as a country, and the autocratic theocracy that rules it to stay in charge. Not only it managed that so far, but it now effectively controls the flow of all exports going through the gulf. It is an actual victory.
US' goals were unclear. A lot was said. Regime change? Stop Iran's nuclear program? Stop its support to proxies in the region? Take Kharg Island? None of that was done. It was a deafeat.
Israel's goal is murder. It murdered a lot of people during this war. Double points for murdering children. I think Israel can also claim victory here.
