O Brave New World!
US will hold N. Korea responsible if it arms terrorists: " President Bush said Wednesday the United States would stop North Korea from transferring nuclear weapons to Iran or al-Qaida and that the communist regime would then face 'a grave consequence.'" Bush refused to spell out how the United States would retaliate. "They'd be held to account," the president said in an ABC News interview.
This sounds like a new doctrine of deterrence. If not, it's a least a first cousin. Here's a threat to retaliate not against a proxy, but a state sponsor. This subject was discussed in the Belmont Club about a dozen posts back. Discussion centered around whether it was possible to assign a one-to-one correspondence between the source of a nuclear weapon and its use by a proxy. Apparently the President feels it is possible -- not to say easy -- but at least theoretically possible.
We're not in Kansas anymore.
