They made so many acts on Chinese province of Taiwan and China itself in the past years such as to allow official visiting of Taiwanese president, ministers and US secretaries on each other's land. So what ? Nothing happens, US dare not to let Taiwanese president and ministers for official visits to US.I am not a war general/ veteran and I did not say there will be a war. So, I have no answer to what you are presuming in your post. But, you anticipate a war and China annihilating American ships just by throwing a few missiles.
Better for you to read and understand why the US Congress has adopted a Doctrine name the Burma Act, its scope, and its applicability. I hope you will get an answer to your inquisitiveness after reading the Burma Act.
