Sorry,
Soccerman, didn't mean to jump down your throat. I was a little edgy after reading some other topics.
Seriously, though, space is ALREADY populated with military hardware in the form of spy satellites and communications satellites. The protection of those assets is essential to effective military operations on Earth, if the U.S. is to maintain technological advantages over its adversaries. If our enemies develop methods of challenging our assets in space, and we have no defense, we are putting our servicemen in danger. The time to develop technologies for such defense is now, BEFORE we have credible threats to our satellites (which intelligence says our enemies are developing).
I don't think it's Bush's intention to boost the economy through military spending. I think Bush, and many others, rightly feel that the US military needs some redirection and more funding to rectify some of the problems that were allowed to fester during the Clinton years. The refocusing of strategy into space and into rapidly deployable forces points to a change in administration thinking on defence and not to economic policy. A favorable byproduct of such a reformulation of US military strategy could indeed be a boost to the economy by increasing the defence contracting sector, but I seriously doubt that that is the primary goal.
