Sad But True
We will always need a military to stand as our physical defense from harm by others. As our world perfects itself, we will nolonger need to protect ourselves from other humans. But there are other species in this galaxy, and they may not posess the wisdom that allows all intelligent life to move foreward and work together. Some will surely be more advanced technologically, and socially immature and therefore choose to conquer and destroy. Just look around our own planet and you will see that we can allready do that on a planetary scale.
Walk Softly And Carry A Big Stick
I believe we have the means to be the ones to have the BIG guns in this galaxy, and yet also remain socially defensive. We will keep our military 'know-how' a secret until the moment we need to use it. And if we don't need to use it, nobody will know what weapons we have. (we will not be bullies) Nobody will ever convince me that my military service was a waste of time. As senseless as it may seem, all it will take is one species with a bigger stick, and the will to use it, to put an end to all of humanity.
