Killing people is wrong, therefore we should refrain from technological advances on our own side? Yes, you definitely are placing such a high value on human life there. If we're going to fight the war, I want it done with as few US casualties as possible (preferrably as few civilian casualties as possible too). I don't give a damn about how many of the Taliban's fighter we kill. They hurt us, so we're fighting them. This is the way the world works. And I'm not going to apologize for using Predator drones and other technology to advance the war with minimal risk to our own personnel as possible.
Not true. Abraham Lincoln had a son who fought in the Civil War. FDR had three sons who fought in WW2. And many of the former service members in Congress are also hawks (Senator McCain, for example).
I've never served in the military. I have family and friends in it though. My family's fought in every war this country's fought in, starting back when we were still just colonies. My cousin's about to go on his second tour in Afghanistan, after having done three in Iraq, and tours in Bosnia, Somalia, and Iraq during the Gulf War as well. This discussion affects me through my family and friends (if you're asking if I have a personal stake in this matter). I don't see how whether or not I've served changes the facts.
Not that much of our GDP goes to the military. 4.7% for FY2010. In contrast we spend 5.7% of our GDP on education. It's a large part of the national budget (23%, I believe), but that's because of the divvying up of responsibilities and jurisdiction between federal, state, and local government.
