A german's point of view...

[creepy]

But when it comes to anti-satellite or space-based weapons, it is an exclusive group. The US is a signatory of the treaty forbidding the militarization of outer space. As of the present, it's only the Russians who've ever deployed an actual anti-ballistic missile defense system (back in the late 60's?).

The U.S. is a signatory? Then why should it be upset that other countries (that are not signatories) are developing such weapons?

Btw, an anti-ballistic missile defense is VERY different from an anti-satellite weapon system. And a missile launched from the earth targeting satellites is NOT a space-based weapon.

That doesn't mean the US will stop research on potential space-based weapon systems because the last thing they want to do is get caught with their pants down. As that successful Chinese test shows, there is reason for the US to at least have a working solution should the need arise.

You're getting it backwards. Because the U.S. has the capability to destroy satellites from other countries, other countries should similarly arm themselves to protect from possible U.S. aggression. Not the other way around.

The logic should be simple and fair: ALL countries should stop developing such weapons. The U.S. should not be "above the law" in this instance or in any other instance. Of all countries, the U.S. has the LEAST right to complain because it has such weapons (mas may karapatan mag-reklamo ang Pinas kaysa sa Tate).

The best thing would be for the U.S. to renounce all such development with the condition that ALL countries stop doing so as well. And not whine because another country is seeking (or has developed) such capabilities. If anti-satellite weapons are really a threat to "world peace", why does the U.S. develop them?!?!

Still, you have to make a distinction between research/experimental versus actual deployment.

The U.S. government is threatened not because of any debris from the test but because it doesn't want anyone else to have the capability. That is indisputable.
