Eagle Speak and In from the Cold both have excellent comments on the North Koreans' apparent intention to flight-test a Taepodong-2 ICBM. Check them out, here, and here.
I don't think it's a concidence that the North Koreans and the Iranians are both pushing at the non-proliferation regime at once. I would expect that these two countries are coordinating their efforts, and assisting each other both technically and diplomatically. I think Mr. Chavez in Venezuela is in this game also, running diplomatic interference.
Our problems in dealing with Iran and North Korea are a function of diplomatic isolation. With the exception of Japan, Australia and Britain, the US is, for the moment, effectively without great power allies. The liberals blame this, along with the weather and everything else, on Bush. For the most part, our present isolation is an effect of our overwhelming economic and military power, which would produce resentment and enemies no matter who is President.
I supported and support our efforts in Iraq: but we cannot pursue the current foreign policy relying on the continental part of the NATO alliance, that is, the French and the Germans. Those powers are our commerical rivals, and have no reason to give us diplomatic and military cooperation.
I have said for some time that what we need to do is get on terms with the Russians and the Indians. We have done our best to ruin any chance of working with the Russians: why the government is surprised about Mr. Putin's current anti-American tone is quite beyond me, given things like American interference in the 2004 Ukrainian elections, and our footprints all over Central Asia.
Instead of trying to work with the Russians, we have tied ourselves to Europe's diplomatic games with Iran -- which are designed to do nothing but run out the clock while the mullahs render themselves invulnerable with a bomb. The Europeans will not do anything, and will prevent us from taking steps to destabilize the mullah regime. Looks like we are going to stay shackled to the NATO corpse until it is too late.
