Any attack would weaken the chance for a Democrat to be elected president.
Radical Muslims know that attacks while there is a Democrat president would be met by the president filing a police report with the local police department.
There would never be a "Shock and awe" military counter attack in response. It would simply be, "Aw, shucks."
While GWB's open borders have probably exacerbated the situation for the next President, his actions after 9/11 have probably helped significantly to deter further attacks while he is in office. Further attacks while he is President will result in regime change in Iran and/or Syria, they know it and we know it (a little Rush lingo there). But we can look for all hell to break loose 15 minutes after Hillary takes office. Some of it may come from terrorist.
