From the Vice President’s “speech at the annual Munich Security Conference”:http://www.securityconference.de/konferenzen/rede.php?menu_2009=&menu_konferenzen=&sprache=en&id=238:
We will continue to develop missile defenses to counter a growing Iranian capability, provided the technology is proven to work and cost effective.
We will do so in consultation with our NATO allies and Russia.
Nothing really new here, except possibly one thing. I’m probably reading too much into this: it appeared in a speech given in Munich, in a section of the speech concerning NATO. But still, did you notice? Joe Biden’s brief discussion of missile defense made no mention whatsoever of North Korea.
