As discussed previously here:

The same people -- same individuals, same organizations, same publications, same blog sites - that ginned up a war with Iraq, and that have supported ginning up a war with Iran, are settling in for a longer term confrontation with China.

These people need to be judged on their track record. And compared with a confrontation with Iraq or Iran, a military showdown with China would be 10 times as unnecessary and 100 times as stupid.
