Just for the record, what exactly is the Leftist position on this? I mean one day I hear.."It doesn't work" and the nexct day I hear "It will blast countries and were not liek that"...so what is it?
See, Godz you aren't listening.
The fact is that BMD doesn't work and most physicists (you know, scientists who reach their decisions based on science instead of old s/f movies) don't think that it will work anytime soon.
The US government has said that this is their first step to getting space-based weapons though. That part will work because the targets are static. Those weapons would not be defensive and could be used to attack other countries. Given the USA's apparent disdain for the rule of law, it is likely that they would the weapons in another "pre-emptive war."
It has already started a new arms race according to statements made by both Russia and China.
If you'd spend some time learning the facts and thinking about what they mean you would begin to understand why so many are so opposed to this. Most of us have already lived through one Cold War and arms race and don;t want to do it again.
