If the USA is so capable of this war of attrition then why on earth is the nation struggling against Russia right now and also how come the situation in Afghanistan, Iraq, Libya and Syria have not yield the kind of one side results other then basically wasting time and resources and ultimately smearing the name of the USA as an incompetent nutcase that seems to have a hard one for bombing civilians for no other reason then yeah we are basically dumb. Also, you are making the assumption that all these war games of the USA agonist Taiwan yield no other results then the USA losing back is none existent and thus the USA as a nation of its overall parts can simply magically deploy is full might (of which I fight extremely questionable given the fact that the USA right now is struggling to fix their so called best destroyer ship the zumwalt from all there rust problems along with the f-35 problems that are causing major issues all over the place in regards to their overall usability) and defeat China without China planning accordingly along with Russia because in such a senario of a so called victory, Russia be next on the chopping lock because the USA has proven to still be a genocidal nation that wants both Russia and China under there feet.
The USA has already shown that they will go to extreme lengths to anger Russia into a fight in Ukraine so they can appear the hero along with all the abuses hurled against Russia for the pace 5 decades, if the USA does withdraw all its available forces to face China, don’t you think that Russia will use its time to I don’t know, strike the east coast of the USA, wipe out all the us based in Central Asia and the Middle East, cripple the dollar by negotiating with the Middle East to cut off all flow for resources to the USA, aid China due to the USA due to the fact that the USA is willing to go to war over a land that is not even remotely close to USA territory,
Also note that these failures in the South China Sea, the sub marine and f-35 are no accidents, if these things happened either because the USA is incompetent or China got the ability to wipe usa forces with tech that unless you are working within the Chinese government would have easily kept hidden from the world (I mean all that tach they shown in the last few years in regards to advancements must yield military tech that none of up are aware of. If the USA is incompetent enough to get into these kinds of situation, then the likelihood of the USA being ability to deploy is full force is very low given that the USA ability to restock its military capabilities with their homeland infrastructure on the verge of breaking down is going to make a war of attrition very hard, not to mention well the USA needs China to stabilise its economical hell hole, not risk getting cut off from all its goods and other essentials in the event of a stupid war that the USA will start to make themselves look good. The moral of the usa hinges on its ability to buy goods for cheap and the event that inflation skyrockets to the point where 100 dollars equals on piece of bread, no one is going to care about a war over seas when their children are going to starve to death right in fro of them. Also, if China does have the technology require to basically force the USA navy away from the South China Sea seemingly by turning the GPS off and well cause these accidents then still yield no really explanation other then to hide this incident from the media as much as humanly possible, well I can see why the USA is trying to basically push other nations into joining them which really, not many other of these neighbors really would want a piece of China as well because really, they will be taking the brought of Chinas missiles while the USA sits back and sprouts bullcrap like they did during the migrant crisis in Europe from the conflicts in the Middle East. Really, you would have to be a complete nut not to see how many SEA nations wouldn’t want to be bombed in the likelihood of such a scenario day is going to start because the USA has that much of a hard on for bombing the civilians of other nations that they cannot see the views of others and how it affects them.
The USA doesn’t have years to deploy their full might in the western pacific because main nations like Iran, Russia, North Korea, and all other nations that the USA has victimized are going to react and also the economic fragility in the USA is going to really harm their ability to raise funds for such a war and no printing dollars doesn’t mean anything because if the USA loses its world reserve status due to all the abuses of it, well the ability to purchase the necessary resources to block able and force China into submission is simply impossible to purchase because the USA is in such a debt ridden situation that any disruption to its operations to is supply chain on that magnitude is simply going to rip the very foundations of the nation apart and China will obviously use this as an option by dumping all of its treasuries and cutting off all trade with the USA as an initial act to facilitate this crash. The USA simply will not have any ability to do anything with the majority of the nation cannot purchase their own food nor their own necessities if such a scenario happens.
Hence your scenario of the USA being able to focus its full might on China is simply well unbelievable in a climate that well, just attempting to do so will cut the usa from so much of the resources needed to basically function along with the enemies of the USA not using there resources to cut the USA off from the Middle East and all the other resources needed to function and well get some much needed payback on the usa. You would have to be utterly crazy to think that Russia isn’t going to take the opportunity to get some much needed payback against the USA for all the harm they have done and the USA trying to focus its full power to face China (which given its current issues will be all but a necessity) shouldn’t be consider as a winning move for the USA but a critical error that have the potential to sink the USA into the dirt for good because it will open up the east flank for Russia and other nations to strike them at the seat of their power. Don’t think that the USA can focus their power against China without consequences because the situation that the USA is in is not good in the slightest and the USA has many enemies that are just waiting to take revenge while their so called Allie’s would increasingly benefit from the USA not be in in the picture such as the whole Nordstrom 2 situation and cannot be counted on to sacrifice themselves just for americas sake
