According to news reports, Saddam has finally succeeded in developing the bomb. Make that, TWO bombs and counting.
Which gets us to this discussion point (and to my solicitation of your most humble opinion):
New York and Washington, D.C. are just too tempting as terrorist targets and eventually (say, within 50-70 years) either or both will be hit by either a nuclear device or a chemical/biological warfare agent of massive proportions. To strike at these cities is to strike at the heart of the U.S. and must be at the top of the wish list of dozens of well-connected terrorist factions.
It also seems probable within this time span that Israel (Tel Aviv?) will be attacked similarly in some mad suicide mission, state-directed or no. After all, if terrorists are willing to drive a truck load of explosives into assorted buildings, why not a nuclear weapon? Why not trail a mist of anthrax over a major city by way of a Cessna? Surely they must dream of doing such evil and eventually they will acquire the means of doing so. Tick tock…
