"Why is it then that we are continually told that another terror attack is not a matter of "if" but is a matter of "when?""
Because the job is not done.
And cowardly nutjobs like Ron Paul who give aid and comfort to the terrorists and show weakness aren't helping get the job done.
Someone already asked, though you have yet to answer... WHAT EXACTLY IS the job that's left for our American troops in Iraq? A specific, quantifiable job, if you would, please.
