I don't think that a handful of nuclear submarines are going to make a great deal of difference. China is less likely to invade Taiwan than to blockade it and try to force it into subbethan. They're very happy about this deal with Australia. The defense pact actually helped deter China from invading Taiwan. Now, China also seems to be building up their political influence as well. We just saw them serve as mediator between Saudi Arabia and Iran,. How does this deal work in China's favor?
