China vs. US conflict over Taiwan/Formosa Strait

This is an almost 100-year conflict, which made a lot of sense when there was so much currency difference between the mercantile British and the Imperial American government who both had powerful navies to secure Taiwan's independence.  The Taiwanese government has failed in a land invasion with standard firearms or any kind of beach landing already.

The militarization and modernization of the Chinese army are going to give them dangerous military capabilities in which in a war similar to all the others, which has lacked public support over these imperial wars.  Dissidence over the imperial American wars has gone back to 1899 with Mark Twain's protesting the Philippine invasions, which was a waste of time and money, and colonization of the Philippines. 

It is possible to defeat China in a major conflict by knocking out the industrial factories producing the components for war machines and such, however, it is a lot easier for the United States to retreat to Guam/Hawaii at this point to continue to dominate in naval wars if necessary, and not bother on land invasions because they are so much more expensive.  Wars over the horizon are the normal now and it is much easier to fight on the ocean.

The USA can engineer materials overtime to raise the distance of aircraft to 7,000-10,000 miles to round trip into the heart of China to hit mapped outbuildings.  However a land war is costly, so the only thing that can be achieved is disarmament and deterrence of China.  Any real war with China the current voting population of Taiwan who supports non-reunification is ~5,000,000 and this is not nearly the number needed to defeat the PRC and they do not reproduce population fast enough because of the inequality of the capitalist system causes polygamy and lack of population growth, to fight in a future war. 

A good option in this situation is any of these 5,000,000 people who are unwilling to live under Chinese rule should be allowed to immigrate to America and just empty out the Island, and allow the Island to lose its economic productivity as a cheaper and safer alternative the USA could import a major "Tiger" and gain this GDP in the SW or NW or even BC, Canada.  The pacific ocean is a powerful deterrent on its own and the USA owns the pacific ocean and it's very difficult to fight the USA to Hawaii.  Consider my suggestions.
