@ joe: Get used to terrorism

Yes and no.

Yes, in the sense that one death,
or 20, or even 2000, can be absorbed
by a nation of ~ 300M people.

No, in the sense that as technology
advances, and weapons of mass destruction
become available to terrorist groups, and
eventually to individuals, no nation can
withstand, and hence cannot allow, even
a single successful atack; The rule will
be; Get them before they get us.
