They fully realize the danger, they just hope that the NSA and CIA and FBI will catch them first. The 'Rats actually WANT the terrorists to succeed so they can scream about the failure of Bush to protect us. Never mind that they have opposed any type of immigration reform and every attem[pt to secure the nation, the liberal media will faithfully parrot the daily 'Rat talking points.
No they don't. The Rats smell blood over wiretapping, Abramoff, DeLay etc. Whether it works or not we'll have to wait and see, but as long as they can focus on "culture of corruption" that's what they want.
The last thing they want is for events to bring national security to the forefront of people's minds.
