Will We Close the Border Before or After?

Time Magazine has an article stating that one of Zarqawi's captured henchmen has indicated they may try to attack us by way of Central America and then across the Mexican border. Why this is news is beyond me, they will come either by way of Canada or Mexico and it will happen soon. One doesn't have to be a super sleuth to figure this out all one has to do is look for opportunities and odds for success which would be pretty high if done with even a modicum of planning.
This part of the article is very disturbing: According to a restricted bulletin that circulated among U.S. security agencies last week, the interrogated aide said al-Zarqawi has talked about hitting "soft targets" in the U.S., which could include "movie theaters, restaurants and schools."
If these lunatics manage to do this I hope we have a plan of retaliation in place already, like destroying, and I mean obliterating, one of their shrines. Further, we should let Iran and Syria both know that we will hold them culpable and as the Bard said, "Cry havoc, and let slip the dogs of war: that this foul deed shall smell above the earth, with carrion men groaning for burial."
