This Chinese embassy subplot is getting ridiculous. With the attempt to melt the nuke plants and the stolen warhead, which has a tie to the guy the embassy refused to turn over, the President would tell them to pipe down, because if that warhead is detonated, the refusal to hand the witness over puts blood on China's hand. If they want to talk act of war, one dead embassy chief vs. thousands of dead citizens are not equal.
If, as it seems to me, the nuke hits LA then the Chinese problem will go away too !
How about:
"Mr. Chicom Chairman, please explain why the Chinese Consulate was harboring man with known ties to a terrorist group responsible for millions of American deaths."
Sounds like a casus bellum to me.
