Well gosh . . . why in the world would I be "hung up" on Bin Laden's marching order? How about because the topic we're discussing is 9/11--the anniversary of which we all just noted.
In this case, the Big Fish IS the infrastructure. You can't even go after the little fish until you catch the Big Fish . . . because he's the one who's collecting the bucks for the bad guys. And once more, you have decided to ASS-U-ME "infrastructure". You have decided to ASS-U-ME that those donating through Big Fish actually KNEW that they were supporting terrorism. You're starting off with a whole bunch of weak assumptions.
If small fish are at all smart (and fortunately, many of them are not--which is why they get caught before they become Big Fish), then they're not going to let friends and families know what they're doing. If they do, there's a good chance they'll get caught . . . and never get to the point of the Muslim who sabotaged the plane.
But once more--just to reemphasize: How can anyone dispute the fact that American Muslims simply aren't much of a threat when it comes to doing their Muslim duty--straight from the mouth of the man who proceeded to kill 3,0000+ Americans, just to make the point that he was serious about what he said was the duty of every Muslim everywhere? Since 9/11, only a miniscule number of American Muslims have made the decision--and followed through--to go from being a spectator small fish to a killer Big Fish.
Impossible to dispute that point. The evidence is clear.
Which is why you deflect and choose to make all sorts of unsupported assumptions about how maybe lots of American Muslims are little fish. Maybe most of them aren't fish at all . . . barring evidence that they're actually doing anything fishy.
