On hefting a bomb (conventional or nuclear, of whatever size you might wish) into the likes of Times Square, there are so many options. I wouldn't really want to state them
1, but I don't need to. Some of the capability (give or take the actual bomb, which is perhaps going to be the big breadcrumb trail, whether it's of the Enola Gay or Timothy McVeigh type of payload) has been around for decades, for some variations on the themes there's been recent developments that could now be used in the plan.
Many plans don't even have to work perfectly (like did the 9/11ers think that
they, and not their improperly protected-from fires, would collapse the WTCs?), that'd just be a bonus, and near-miss collateral is often as good a message (like when checkpoint guards and queues suffer the fate they'd have really wanted to bring to bear upon the heart of the protected Green Zone), especially if you're already combining the word "over" with the word "kill".
But anything I've thought about, anyone:
a) Thinking about actually doing something, or
b) Trying to anticipate and guard against those others who would try to do something
...are likely to have already considered and possibly put into their 'possibilities, given the opportunity' tray.
And the (a) group has the advantage (including real-flag, false-flag and probably even false-false-flag actors if you're
really paranoid), because they only need to do what they do the once, sufficiently successfully...
I don't think it'll go as far as many of the scenarios (mainly because the lesser ones are easier to make happen, and also because the first plan that ever happens means that there's no need/ability to repeat an attack against the same target in a different way), but in exploring the phase-space I'd be hard-pressed to rule
any of them out. Even the more (apparently) outlandish ones.
None of this helps discussion, though. So let's ignore that all and go on about
those wacky North Koreans, instead, at least insofar as wbat that does to AmeriPol stuff... (I'm sure that was last night's news, yet that version's only an hour old...)
1 If I could get Google Groups to surrender up what I know I read on alt.(books|fan).tom-clancy in August 2001, maybe slightly earlier, maybe the first week of September... But between X-No-Archive, the possibility of conscious sensitivity behind the scenes, and Advanced Search being awful, I'd have to dig up the old HDD I was using at the time and look for the local download I may yet have.
