so... you're proud of beating a tiny middle eastern oil dictatorship, illiterate tribesmen and a chinese/soviet proxy? what happened after inchon? "yalu by christmas!" but really it was "run back to the 38th". you beat the weak north koreans, congratulations. then what? used the south koreans as cannon fodder and let your general die? in every US war since Vietnam, the war was over before a single american boot set foot on the ground thanks to the US Air Force and Navy.
in terms of the quality of infantry and ground forces, US soldiers are not at the standards of Germany, Russia and China. Russian soldiers clear land mines by running over them and don't give a second thought, do US soldiers have that will? German soldiers will eat rats and fight in subfreezing temperatures without even coats, can a US soldier survive that? Chinese soldiers march 70 kilometers per night and remain absolutely motionless at day to achieve strategic surprise, can US troops leave their humvees for a few hours? In every evenly matched ground war, such as Korea, US soldiers have shown that they simply depend on the air force.
Without the US Air Force, the ground force is actually pretty weak and probably not even a match for Vietnam.
