Manhattan would be easily blown, remotely. Place a time-charge beneath a car at the head each principal subway line (which commence in other boroughs), set to blow at the main stations. For the West Side, supplement with a charge in the PATH train from Jersey. For the East Side, supplement with another in the LI Railroad from the Island. Forget anything above 86th Street, they'll applaud; like the WVA and VA hillfolks will hooray the destruction of see-navel DC and its high-pitch babbling wonks. As will anyone of any capital (or high-tech vale), globally, not drunk with power or mad to get it. That's what horrifies the powerful about of terrorists: they're both spitting images of their opponents. Both willing to kill indiscriminately for vainglory of blind faith and ambition. Both willing to betray their kind for a step up. Probably the stealth bombers will led by a highly trained ex-, or covert member, or Top Gun grad, of a duly authorized terrorist, wing, sub, cell set up to kill for a culture's honor and commerce -- for blood-drenched national security. USG and IraqG, any G, joined at birth, never separated, working in concert.
