China doesn't have the funding or supplies to support most of their military, and in event of a NON nuclear war, america would devastate the Chinese mainland in months without a doubt.
The real "challenge" would be with Russia coming to china's support, in which case russia would also have to sit the fuck down and suddenly realize america would control every inch of the skys with superior planes and superior numbers, they would insantly control the seas just by numbers alone, and our heavy armored vehicles are superior as well. Ground troops would tear up russian resistance as well, with the same outcome but taking much longer if an actual invasion of russia occured.
However after this, america would DEFINATELY need some time to get their shit back together after beating russia and china.
