There is a reason we send men to the moon. The value of there observation and ability to adapt and re-task (currently) is far superior to machines. As for unmanned attack aircraft. There is a delay from the remote control site to the plane. That delay both ways says that the ability to pull 15g's to get out of a bad situation probably will present itself too late, or because of the delay you will need that speed of evasion.
Not to mention the de-humanizing effect we have seen already with the video game war where the warrior has no skin in the game. The human equations that should be there as a deterent to war, aren't. That is probably the biggest risk and failing of this direction. Of course those who just want to win and don't care of the cost to the other side, that can engage in riskless carnage, will attract the very people that would naturally be culled out through the process of war. That culling of sociopaths is part of our natural evolution. If you take away their natural predators (man, the other side) then as with all species they will overpopulate and strain and break there ecosystem.
