My Guess?
We know there are established hezbolla, Hamas, etc cells in the US, no doubt in NYC.
Exsisting cell has the materials, and need agents to pull off something, since the cell people here (leaders) dont want to go all boom-boom themselves.
Now the 11 are here.
Keep an eye out.
Remember the latest "video" from Jezbollah TV or whatever, Al-Zero yammering away with the photo of the WTC collapsing in the background, and photos of Atta et al posted in martyr fashion...... My first impression of that was IT'S A SIGNAL. Something's coming down....
