If that would be the case,why would US expand all out effort to maintain arm embargo against China lobying hard to keep the embargo. Accomodating nuclear India to the point of hypocrisy but at the same time sanction Iran because she want to developed nuclear energy
Declaring Taiwan as a part of China but at the same time having security arrangement with Taiwan and making noise about coming to the aid of Taiwan
Encouraging Japan to rearm to the the point of allowing Japan to change the postwar constitution and making arrangement with Japan to help US navy in emergency
If that is not containing I don't know what is.
1. You were talking about the "Western world", not just the US. I said it was nonsense that a coalition of powers was seeking to contain China. China is a concern to the US in part due to problems over Taiwan. The US is committed to helping Taiwan, so obviously it doesn't want to make its own job that much harder by allowing China to buy whatever it wants.
2. India is already a nuclear power - Iran is not. Iran has also made threats to destroy Israel - is India nearly as beligerant? Not really.
3. If the US really wanted to contain China it would subsidise Taiwanese arms shipments - as it is, it often charges
more than it does its other customers.
4. China is not the only security concern in the region - North Korea is more of a current problem. Besides the US doesn't want to have to look after Japan. It would much prefer it if it could rely on Japan for military support the world over. Other countries like the UK have supported Japan's efforts to normalise itself - and we don't care nearly as much about China as the Americans do - because we want to see Japan helping out on deployments as well, whether its peacekeeping, disaster relief, or whatever.
China's "threat" does factor into US decision-making, but it is far from being the overriding factor.
On a side-note, although I do not believe the US would attack China without good reason, the same applies the other way.
