Pyongyang, North Korea
Dear Mr. Kim,
It has come to my attention that you have been spending huge amounts of money and starving your people in order to produce nuclear weapons. My message to you, your friend Mr. Ahmadinejad, (whose address I've lost, feel free to share with him), and others in your Axis-of-Evil is simple: Don't bother, as the events of the past week prove you don't need them.
In case you weren't paying attention, about a week ago a couple of nutcase brothers, for reasons not yet known, set off a couple of bombs at a major event in Boston. It was tragic, and Boston recovered pretty well, after a superb handling of the immediate aftermath of the event.
Then on Thursday night and Friday, with one suspect dead and the other on foot and believed to be injured, we went collectively nuts. Buses and trains as far away as New York (about 320km/200 miles away -- futher than you are from your enemies in Seoul -- if you don't know the geography) were stopped, inconveniencing people hundreds of miles away for no discernable reason. Airspace over Boston was closed because... well, I'm not sure why a guy on foot in a suburban township of the city would force a closing of airspace, but it did. As far away as Manhattan, the Central Park Traverse was closed and evacuated for a while so police could "investigate" a car that was deemed suspicious because it had Massachussets plates and a couple of youngish guys inside, this even as the drama in Boston was drawing to a close on Friday evening. [Note for the future, if you're planning to steal an escape vehicle, find one with out-of-state plates and head for Manhattan, because that'll fool the NYPD!]
In Boston things were even crazier. The entire public transportation system was shut down immediately even though the closest station (Harvard Square) is more than a mile away from the suspect's last known location and would be easy enough to guard. Eventually the whole city was shut down and everybody told to stay home, even though there was no reason to believe the suspect had any way to get over the relatively few, and by this time well-guarded, Charles River crossings to get into Boston proper. [Only Dunkin Donuts stores were allowed and encouraged to stay open because apparently the local public safety apparatus cannot operate without them. Another lesson terrorists should keep in mind: attack the donut stores and bring our emergency response system to its knees!]
Our emergency responders and their leadership already knew a truth that wasn't immediately shared with the public: at that point it was one crazed 19 year-old kid who may or may not have had a weapon and ammo with him, who was believed to be wounded, in a section of town that was rapidly locked down and cordoned off. Yet a whole city shut down for 24 hours, with major infrastructure closures and random stoppages extending to distant cities.
The lesson is simple Mr. Kim. You don't need nukes to destroy us, or even threaten us.
