A wouldn’t say the Iraq finished in “a few weeks.” They knew if they just left it would go back to the same business as usual. So the USA stayed for years playing Sim City. Trillions of dollars all said and done doesn’t seem like a win. These proxy’s are just that, proxies, because foreign policy on a grander scale is harder to accomplish like with China or Russia. USA won one proxy in the region but it’s more akin to winning the battle not the war. Iran is showing this as I type.
