Lieutenant General
You obviously live in a hole and never seen the real world.
You HUGELY over estimated the average american intelligence.
1952, Korean war, lots of casualties, but american quickly forget about it and got drag into Vietnam war, which lasted for a long while and with massive casaulties and again after the war ends, americans forget. Then came 1st Gulf War and then Afganistan and 2nd Gulf War..... Did American public remember? of course not. Did they support it? HELL YES. They love getting maimed and killed! There is no other explanation because they just keep voting in parties that gets them into wars for no good reason.
There is an old saying - "You live by the sword, you die by the sword".
You obviously are stuck in the hole of no return. You need a 9/11 type of incident in order to get even 50% of the American people to support a war or conflict that they know could handle without the mess of Vietnam and Korea(as in high casualties). Because the main drive for that support is through hate of Muslims and blaming of Muslims for 9/11 (although many wouldn't admit it in public). Even the most hawkish Americans are not going to want to go to war with China for whatever reason.
