You're so invested in this hobby that you can't admit you're wrong. Okay, if it's so easy to do TODAY, then why doesn't GWB run down to radio shack and buy all the lasers he needs, throw 'em into orbit on a Delta rocket and scrap the missile to missile interceptor he's building now? Common sense would tell you that the atmosphere plays a HUGE role in dissipating laser energy. It's not hard to see or understand.
