Of course, according to which country you talk to, the blame should be placed on the other for the incident. What brought this chain of events to where it is currently is a long and involved history of interaction between the U.S. and China. Most recently, relations have been strained as the U.S. has been working with the Taiwanese government on selling them four naval cruisers equipped with the sophisticated anti-missile Aegis system.
China sees Taiwan as little more than a rebellious province.
Make no mistake, China is a very real and present threat. This threat increased during the last presidential administration where, certainly under a breath of pure genius, our former president sold the communist government valuable military, intelligence, computer and nuclear secrets for campaign contributions. One of these secrets was the Cray Supercomputer, which is so powerful that if you were to put in the specifications for a simple Bic pen in two days it would give you a schematic on how to make that simple Bic pen the best pen in the world. When engaging the Chinese at any point one must keep in mind that they are a subversive and amoral aggressor that is lying in wait for the right moment to pounce and devour their prey.
