And how will leaving keep the M.E. terror monies and drugs coming in through Mexico?
Ron Paul's and Duncan Hunter's plan to build a serious border fence-wall will do far more to secure the Mexican border than any war 7,000 miles away, IMHO.
Like 10-to-1 more, IMO; and that's even assuming the Iraq occupation actually reduces the problem at all (for all we know, the continued US presence in Iraq may serve as a fundraising and recruiting boon to radical Islamists).
