First of all, there's no way we were going to lose. We had too much air power. Second of all, look what Patton accomplished as commander of the 7th and 3rd armies. Thirdly, the North Koreans and Chinese wouldn't have been able to use his aggression against him because of our air power.
Actually, and keep in mind this isn't MY opinion but the actual positions of those who actually fought this war, air-power while effective would NOT have stopped a breakthrough or route. It didn't the FIRST time around and quite logically it was felt that the enemy would and could 'surge' to suppress UN air-power given we couldn't effectively suppress HIS air power in China. As has been pointed out our direct air-power on the peninsula was VERY vulnerable, along with our logistics tail, and we were well aware of that fact. Naval air-power was limited and anything outside the peninsula would be 'late' if it arrived in time at all
As it was our air-power was constantly having issues suppressing Chinese aggression normally which was a big part of the reason we couldn't get 'more' aggressive.
Yes I'm well aware of Patton's performance and he had several advantages there he would not have in Korea. Which is a point you keep missing, I suspect on purpose. Note that WHEN he was denied logistics or superior support he did NOT in fact do as well as when he had such and keep in mind Korea IS a "side-show" and not the main theater and was treated as such. It would be NO different with Patton in charge. It can't be.
Lastly why would you assume our air-power would prevent the Chinese, (at this point they were in full control of all combat forces in Korea and the North Koreans were regulated to duty IN North Korea because they Chinese didn't trust their abilities) from exploiting Patton's well known aggressive tendencies? The Germans did it several times including delaying his relief of Bastogne by 'dangling' opportunities in front of him he took despite allied air supremacy. He got his (his units actually) nose smashed several times but in the end they couldn't stop him. In the case of Korea he's got nowhere to go and nothing to do it with so he's in effect going to keep smashing his (his units) nose into the wall.
I already have. We dropped 635,000 tons of bombs during the Korean War, almost as many as we dropped in the Pacific Theater of World War II fighting a much more powerful enemy and in less time. That should've been more than enough to defeat North Korea and China. The problem was we didn't take advantage of our air power by being aggressive. The Army parked itself on the 38th parallel and sat there for 2 years.
Eh not you simply dropped a opinion with no supporting evidence, (and most of it's been refuted as to your interpretation) and made the assumption that dropping high explosives somehow means the UN should have 'won' because of that and a suggested commander who in fact would have had the same handicaps and drawbacks to deal with and far less suitability either as an overall commander or battlefield commander. (Korea is not Europe and Patton specifically trained himself and his units to fight in the latter not the former) As has been pointed out the Army did NOT in fact 'park' itself on the 38th parallel and was in fact actively trying to move forward. Our 'air-power' was sufficiently stretched simply suppressing the enemy ground forces and logistics and did not have enough left to support 'more aggressive' operations. Your constant assumption that it did is not supported by the facts or history.
Try and understand this point: The air-power we had was barely sufficient to suppress the enemy. To support an 'more aggressive' campaign would have required almost double those forces committed by ALL UN combatants and those forces would have to be drawn from Europe which would have significantly weakened Allied defenses there. And that is JUST air-power, to force and effective 'aggressive campaign' would have required additional armor and infantry again having to be drawn from Europe with the effect of (again) significantly weakening Allied defenses there. Who was 'in charge' of Korea didn't and wouldn't matter at that point.
Air power couldn't and can't take land away from the enemy, only boots on the ground can do that and only if they are properly supported. No matter what Korea was NOT the primary area of importance and therefore it was a secondary front and given that priory and support. Comparing Korea to the Pacific War is a false comparison as there was no way to isolate and cut off support and supply like we did with Japan. Further China WAS 'as powerful' as Japan in combat power BECAUSE it was fighting the kind of war it had been fighting since the 1930s on its front doorstep against a foe who was not going to commit the same combat power it had against Japan because Korea, (and this is a major point that can't be stressed enough) was NOT the main theater and China not the main enemy.
There is a point where dropping more bombs simply rearranges the rubble and if the enemy hasn't given up yet he's not going to and more bombing won't help. Neither will a 'more aggressive campaign' if the front is already stalemated which it was by the beginning of 1951.
I think the disconnect here is that you are assuming that the US put as much 'effort' into Korea as we did Japan which is far from the truth and that somehow more 'aggressive' action would have somehow made up for that lack of commitment. It wouldn't and it didn't because Korea wasn't the main focus of our efforts.
Yes if for some reason the US HAD committed to total war over Korea we could have and would have pushed the Chinese back and likely 'freed' Korea. Meanwhile Stalin who would have to come to support China would have taken parts of Europe and caused the US to back off just as the Allies feared would happen if they took their eyes on the 'real' prize of Europe. The Commies still 'win' in the end and no one in Europe 'trusts' the US to protect them from Communism. No it wasn't going to happen. Ever.
