  1. "Us conservatives?" by Anonymous Coward · · Score: 5, Insightful

    Don't lump us all together with you. I'm a staunch conservative and considered the justifications for the Iraq "war" more or less fabricated (including the WMD charges.) The world is not as black and white as you seem to think.

  2. real-time satellite imagery analysis? by spiritu · · Score: 5, Insightful

    Have you any idea the amount of space required to store this stuff? Bandwidth costs?

    Let's say you have a (currently non-existant) 1mm imaging platform on a satellite. 1mm per pixel of resolution allows you to identify most things fairly well, but you still might have trouble reading a newspaper's body clearly. Headlines would come through okay - keeping in mind, of course, that you have to make the shot obliquely to get some sort of an angle on it - straight down doesn't help here. Now take a picture of a square 200km by 200km. How many pixels is that? Let's say you take that picture with 24 bits per pixel denoting colour (and not, say, the way you would do it which is with more than three bands... but I digress). How many bits is that?

    It's easier, by far, to do things like fly over the area you want at a less sexy height, like 20,000 feet, with a high-end remote imaging and sensing platform mounted inside your medium-to-low end plane. 500TB cartridges store a good amount of images, and you can jack them directly into your central machine back home while the computers go to work analysing the data they contain.

    It also costs signficantly less.

    (or possibly because the government isn't ready to revel the information)
    You have got to be kidding. If the goverment had that information it would be rammed down our throats 24/7 for the next month as justification for the war in the first place.

    and they probably also moved them to other countries

    Yeah I can just see the head of some bananna republic thinking to himself that despite the fact that Sadam was universally hated in both east and west and the most powerful army in the world will invade on the even the assumption of possession of these weapons why not hide then for him. What harm could it do eh ?

    Did Iraq have limited chemical weapon capability yes, probably developed from Antrax sold to them by the US. This is where the US certainty come in. They 'know' because they provided the foundation.

    Did Iraq they have WMD? more than likely not. Does it matter? NO the US has access to the Oil, all else is irrelevant now.

    Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
    What truth?
    There is no dupe

    Funny, I thought the US military stopped using draftees after Vietnam because of the way that citizens were getting pissed off with the whole sordid mess.
