A literal war with China would destroy a good chunk of the planet. "NATO" is a joke. It would be US vs. China, which sure the US would probably "win", but they'd also likely get hit by several nukes. So would Japan and quite possibly Europe too. Also any type of "ground war" with China would be a disaster. US was having headaches with freaking Iraq and run down Afghanistan. 

Reduced need isn't little need.  In fact, with people buying new smart phones every year, the need is still pretty massive.

China has nuclear missiles. US has nuclear missiles. Nobody's gonna attack anybody. And other countries will surely avoid being dragged in this hypothetical mess. People who don't understand how nuclear dissuasion works should stop trying to spread fear on internet. And even if you don't understand nuclear dissuasion, the mutual economic dependance between US and China is more than enough to stop any overly agressive behavior.

The only way US and China could "go to war" is if China cross the line and invade another Asian country (the tensions in the region are really high). And even then, the US army wouldn't intervene directly. But once again, China has a lot more to lose if they choose the military option when they can easily continue with the economic and political option, so this scenario is unlikely too (but less ridiculous than the US/China nuclear war).

You realize that's ~10% of the US's debt. Hardly enough to bring the US to its knees.

China and USA needs each other, but USA needs China way more than China needs USA.

Different types of conflict, requires different type of analysis. China is not battle proven.

Conventional Warfare is not Guerilla Warfare. Just because US didn't defeat bunch of dudes wearing the same clothes as civilians, doesn't mean they can't wreak ones wearing uniform. 

Look people. Here is proof just how good of a brainwahsing tool the mainstreram media is. Oh Snoopy, you and your little dreams of being part of something grand and righteous. Let me guess, Vietnam was also just a heartfelt push for democracy, right? 

No wonder the US got to the point where it is today considering that people like you have the right to vote.

Really? Do you think that the US military would have a chance of actually destroying China? My god people its the 3rd most modern military in the world, with the biggest population to boost, and you still think that the US would stand a chance on its own soil. It is also has a nuclear arsenal to back them uip with full ICBM support to boost. You have to stop to sniff your own propaganda poo for legal highs.

You have to start reading and interpreting before putting words on my fingers.

Did I state where the eventual battle would occur?

I think China would have a hard time solving logistics problems in the battlefield let alone tatical warfare.
Waging war is not just having weapons, experience and know how go a long way.

You've fallen prey to one of the classic blunders, the most famous of which is "never get involved in a land war in Asia", but only slightly less well known is this "Never go up a against a Sicilian when death is on the line!"
