  1. Re:They're wrong on The Drone War · · Score: 2, Interesting

    Unwittingly, though, you've highlighted perhaps the fatal flaw in Katz's argument (beyond the fact that it's ten years too soon): no numbers of drones will ever change one fundamental premise of warfare, namely that aircraft can never capture or hold territory. Until drones can walk, attack and defend, infantry and armor will still be the mainstays of armed forces.

    No, but drones can uterly obliterate territory such that it is no longer worth holding on to -- and that is what US airpower has been doing in Afghanistan.

    During the European expasionist phase of several hundred years ago owning as much territory as possible was necessary as so much of the economy was based on ownership of natural resources. The global economy has reduced that requirement considerably, the US does not need to accumulate large amounts of new territory to survive -- and their military capabilities should reflect that.

    In most any modern conflict all that is needed is a small piece of territory to use as a refueling or resupplying site & a place to launch drones from.

  2. Re:No fear, the galaxy's safe. on Black Hole at Center of Milky Way · · Score: 1

    [quote]The fact that the Milky Way is a spiral demonstrates that the orbit is degrading[/quote] Spiral galaxies do not degrade, this was recently studied by someone who was looking to see how they stay together when it should be that the stars at the outside have to orbit much faster then the stars on the inside to keep the galaxy together, but it was observed that they do not. It was found that it stays together because the stars in the centre of the galaxy are not always the same. They all rotate in circles which bring stars at the outside near the middle, and the stars in the middle in turn rotate so that they go to the outside. So the orbital circumfrance of all the stars is close to being the same and the galaxy stays together. dan.
