Threat to Humanity

I am a constant critic of military spending. The Euro and Japanese fix of 1% of GDP seems like plenty, and in the case of Japan more than needed.  Cuts to the Free Electron Laser and the railgun are definitely a threat to humanity. When the aliens come even though they may be advanced, we all know that its all about energy delivered to the target, and a missile is sure to be low tech to a civilization that can travel light years and still pack a punch.
