if you said the American soldier are that good, then they will come right away. but we also have to consider the cost of life each soldier in USA and China. The cost for each US soldier life is much higher than Chinese soldiers. that is the reason why US soldier do not want to fight on ground. they prefer to fight on air. If they have to fight on air, the cost will be even higher. It is because of longer supply line and unpredicted Chinese air force and missiles. US do not want to fight this war, and US is just talking.
No way US will win this battle when this battle is so close to Chinese border.
