Using only 9 lbs requires capabilities of the highest caliber. You don't just
learn how in college. Publicly available designs call for much more.

Plutonium dust poisoning kills you in a matter of a few days. Actual physical
skin contact with the weapons grade metal will kill you as quickly. Funny thing
about arabs, they have this cultural thing against dying in bed at a young age
(at least the bedouins do).

Even the US doesn't make half megaton weapons any more, and those we did make
once were very difficult and expensive. We only made megaton weapons because of
missile and reentry vehicle technology constraints in the 50's and 60's, and
they don't exist anymore. All of our weapons range from 50k - 250k tons.

Simple dumb ICBMs are a misnomer. Scuds are tactical missiles, not
intercontinental, and they are lucky if they land within a few miles of their
targets. Extrapolate that to a longer range system, and you are lucky if
Akhmed's ICBM is going to hit the right state. Completely useless.

My laser battle stations are small nukes with dozens of xray waveguides
surrounding a heavy sheilding shell. You can launch literally hundreds of these
from the bay of a space shuttle, and they can take sand abrasion as a matter of

Actually, mechanical shutters are being used now.

hardly. laser technology is a booming industry for health care, for industrial
cutting and welding, all sorts of things, plus you've got the launch laser
program as well... there are way more job openings now for laser research than
just a few years ago.
