Excellent post over at The Belmont Club today on missile defense and deterrence. Well worth a read.
UPDATE: In the comments:
It’s a little disturbing when a major Presidential candidate’s first instincts after the Iranians test 9 long missiles are to blame his government for not engaging in direct talks. The real story here is to ask why, if Teheran has no WMD ambitions, it has any ballistic missile program at all. Does anyone actually believe these expensive missiles are going to be fitted with conventional warheads? That would be so cost ineffective as to be implausible. Any reasonable person, looking at the situation, would regard the firing of the 9 missiles with alarm. I think BHO’s reactions are almost unnatural.
