I still believe we are in the early days of a much larger conflict...sort of like the late 1930's in Europe and the western Pacific (Japan in China).
If we do the right thing (ie. take the fight to these terrorists and their supporters without let up, reverse course on the PRC, get sane about our immigration policy, stem the flood of our offshore outsorurcing/manufacturing, and hold fast to our own unalienable rights in the process) we can still avoid the worst IMHO.
