China Tests Anti-Satellite Laser Weapon 552

Posted by samzenpus from the the-people's-laser dept.
schnippy writes "U.S. intelligence agencies believe that China has successfully tested an anti-satellite weapon by destroying one of their old weather satellites. The test, if confirmed, would be an order of magnitude more provocative than earlier reports of Chinese blinding lasers being. Arms Control Wonk has a good writeup on what this will mean for U.S. policy."

    The USA already has this sort of capability ... so why is China having this procative ?

    Or is it OK for the USA to have it but no one else ? I suppose it depends on who you consider the bad guys. I note that China has invaded fewer countries in the last 50 years than the USA has ... so what is the answer to the question ?

      The same reason that Iran's nuclear ambitions are deemed provocative. Apparently only the west is allowed anything nuclear or dangerous - everyone else has no right, apparently. And even then the US has a right to everything, and the right to deny whatever it wants to anyone else. "Land of the free" needs to be updated - may I suggest "Land of the free (to dick on everyone else without the burden of a conscience pissing on your parade because the US is always good and right and never does anything bad to everyone else who are just jealous and should be grateful that the US saved everyone's ass in every war ever fought at least that's what's been drilled into everyone's head since being kids)". Pretty catchy, huh? :)

        Yes Gulf War II was a big disaster. However, if the situation ever stabilizes the Iraqis will have a chance to guide their own lives. China's policy in Tibet is to weaken the local populice by flooding the area with Han Chinese immigrants. I suspect that most Tibetans would like to control their own future if possible but at this point they'd be glad to just not watch as their culture is destroyed in front of their eyes. I don't see that kind of cultural assassination going on in Iraq.

        The US is actually doing *exactly* that in Iraq: Do things our "democratic" way or we'll stay here and keep killing people. You'd see this if you'd actually look at things happening from a distance. The current not-yet-civil war is a direct result of the US removing the one authority figure in charge, and trying to democratize the country. I personally believe that Iraq isn't A> ready B> helped with democracy.

        You can't force two peoples (in this case mainly divided along religious borders) to work together if they don't want to, and haven't in known history. This is simply an enormous mistake in thinking.

        Democracy is what works for *us* (most of the time anyway), but forcing that on other people and countries should not be the way to propagate it, I think.

        Feel free to disagree, but that's my (possibly biased) point of view.

            When that actual war was fought, Bosnia didn't actually even exist yet. The reason it 'works' now is because that country was split up in several parts (Servia, Bosnia/Herzegovina, Montenegro, and it feels like I'm forgetting one)

            These splits have been mostly made between ethnical group lines, and they're now moderately peacefully living together, although it's not exactly all 'pacified' yet.

          As an American who put in over a year overseas, I know our foreign policy reputation at this time. It's not kind. I have been recognized on the streets as an American and confronted on my political beliefs. I'd like to think I gave the "right answer", but I honestly don't know what would have happened a few times if I had expressed support for my president. Let me just let you know, there are many of us (maybe less than 50%, but more than 10%) who believe the French were right in holding off invasion plans and who believe the United Nations was founded in order to prevent another World War II. A seemingly unending bureaucracy it may be, but it's checked by the majority of countries with a last sanity check of the consensus of a diverse group with the most vested interest in a stable world.

          We're fighting to change the political future of our country. It's slow, and it's built upon a mountain of vested interests in large corporations and minimization of energy insecurity.

      That is a mere triviality of a reason. Just look at recent history regarding the US's foreign policy in action. Iraq hadn't done anything directly to the US, yet they were ripe for invasion. Not doing anything to the US doesn't guarantee a country's freedom from being fucked with by the US. China, just by demonstrating it could take out a US spy satellite - note they don't even have to do it - makes them a massive risk to the US, which means they're "fair game" for a more bitchy one-sided, unfair foreig

    The only time a laser is mentioned in the entire article is

    "Neither the Office of the U. S. Secretary of Defense nor Air Force Space Command would comment on the attack, which followed by several months the alleged illumination of a U. S. military spacecraft by a Chinese ground based laser."

    So the only laser involved here is one that is capable of illuminating, target painting, targets - not destroying them. The title is more than a little misleading - can we get an adjustment on it perhaps? Something like "Chinese successfully test anti-satellite weapon"?
