Sure it can. If at war the U.S. Navy can shift its fleets to the Pacific. After all the ships are all mobile. Other countries can take our place like Britain, German, France, etc. Unless Russia intends to invade Western Europe while we are busy fighting China in the future. But I doubt that. There are limits to what Putin can do. So I asked again, how many carriers, destroyers and nuclear submarines do you have? If you can't answer it, then don't waste time spouting nonsense.
Japan tried that once. Doubt China can do it as well.
It takes more than a billion people to achieve the amount of GDP to America with only 300 million. It be like saying India with a billion and Australia only 25 million have the same amount of GDP but does that mean India is rich as Australia?
US aircraft carriers can easily be taken out by our ASBM (yes it does work and yes it has been deployed).
By the time Yankees shift their ships (not as easy as you make it out to be) the war would be already over.
Besides we have 60+ submarines that are world class and dozens of surface ships that are world class. We have anti-space weapons, cyber warfare capabilities, electronic warfare capabilities, hundreds of drones, hundreds of world class anti-ship missiles delivered from ships, air, ground, world class radars, world class SAMs, etc etc etc
Japan wasn't a continental power with 1.3 billion people. We have a population that is bigger than the ENTIRE western world combined! Bigger population means bigger middle class and more tax revenue base to spend on military, more man power, more engineers, scientists, etc.
Actually per capita GDP is irrelevant in geopolitics. Its what resources a nation has in absolute numbers and if they have a bigger population then thats an advantage.
America is not coming within touching distance of China in the 21st century. America will be lucky if it even represents a challenge to China in 30-40 years.
China has overtaken the US in many indicators that no one else has in the last 100 years.
You met you match in China!
Besides, we have already defeated the US military, something Japan never managed to do.
