Sure, but what should we do? Get out of the cities? Go live in cornfields?
What we should do:
1) Go like hell on completing NMD
2) Revive the Civil Defense Program
3) Beef up attack sub fleet even more than the current POR
4) Massively beef up ASW capabilities (or more accurately, vastly speed up the already planed revamping)
5) Find and expell PRC agents and infilitrators
6) Stop tolerating all aid given to terror states and terrorists by the PRC and Pakistan and publicly call them on it
7) Incrementally shut off trade with the PRC while in parallel ramping up trade with India, Thailand, Philippines, and Chile
8) Recreate SEATO but this time replacing Pakistan with India and adding in Taiwan, Japan and Israel
9) Conduct a major review of all military systems for EMP withstanding capability and undertake a crash retrofit program
10) Revive work on IRBMs - sub launched (already planned, witness recent work awarded to Lockheed - Martin), sea surface launched, air drogue launched (note past successful demo of this with an ICBM at Vandenberg) and TEL launched. Yes, that would mean that we are tearing up the INF Treaty. The INF Treaty is rubbish - Pakistan, Iran, the PRC, DPRK and a number of other soon to be nuclear states are non signatories, putting us and *our forward deployed forces* at a distinct disadvantage. Plus, I strongly suspect that some of the former Soviet states are cheating on it.
How's that for an action plan? ;)
