IF THEY SHOULD BAR WARS, PLEASE LEAVE US THESE:

Missile shield research to enter development stage (Japan Times, 10/11/04)

Japan has decided to develop components for interceptor missiles with the U.S. amid pressure from Washington to move forward from joint technological research on a missile defense system to the development stage, government sources said Sunday. [...]

Japan and the U.S. agreed in a so-called two-plus-two meeting of defense and foreign ministers in September 1998 to begin joint technological research on a missile defense system.

The two nations began the research program in 1999 for a system to launch interceptors from Aegis-equipped warships. Japan has spent 15.6 billion yen up to fiscal 2003.

Meanwhile, the government decided last December to purchase from the U.S. and deploy a missile defense system due mainly to threats from North Korea.

The joint research covers four areas -- infrared sensors for identifying and tracking missiles, high-performance shields to protect interceptor warheads from air-attrition heat, second-rocket propulsion units, and kinetic warheads for destroying warheads of incoming ballistic missiles.

While worthwhile, missile defense shields aren't going to be the last word in warfare for long.

"Thor's Hammer", a concept for space-based kinetic energy weapons, couldn't be defended against by missile-based missile defense shields.

One would need very quick and quite powerful energy beam weapons, such as a laser or maser.

And just who is going to have the ability to put "smart crowbars" into high orbit? North Korea? Iran?

Hint: Probably the same folks who invented and deploy self-forging tank-killer projectiles.

In terms of ability: The US, China, Japan, Russia, Israel, Canada, the EU.

In terms of desire, combined with an ability to pay for it: The US, China, possibly Japan.

Orrin:

You believe that missile defense systems are possible and practical now, but not that the future will bring us affordable "helper" 'bots ?

There's a big disconnect between those two positions.

Michael:

robots are undesirable, not undoable. And, no, I don't think any defense ever works in technological terms. They're psychological impediments.

No defenses are ever perfect. It makes a difference though, whether the incoming is a spear or an H-bomb

Not comparatively.

I have no idea what that means
