And if it can't be controlled in China, then it won't be controlled. Are we to put China in indefinite isolation, including all shipping?
I don't think we have the ability to blockade China, and it would be an act of war to attempt it over their objection.
Right now, economic considerations are still supreme over health considerations, right or wrong. If we were able to shut China off, it would certainly cause a depression here and around the world. Could President Bush survive that? I doubt it, especially if the blockade worked. He would be hammered for overreacting.
I'm not suggesting that he'd put his re-election chances before the country, but he'd be nuts to blockade China today.
