USA has untested military also. What you call experience is barely different from live ammo drill. Bombing Iraq or ISIS is completely different prospect from facing enemy with sophisticated electronic warfare capabilities, air defenses and offensive capabilities, etc. As it is: You can't be sure that F22 radar will be able to operate at all in contested air space, or that Tomahawk missiles won't fall down like flightless birds, is battlefield data networking be your Achilles heel or Thor's hammer. There is no way to know that until you have to face capable enemy in anger. For USA or China
Last time USA faced semi-capable adversary was in Vietnam war and capable enemy in WW2. Rest were just completely inferior and incapable forces.
