I'm just not cool with anything that allows the wealthy, industrialized countries to kill members of poorer countries with absolute impunity and no risk to themselves. If you think your cause is worth killing people for, you ought to be willing to put your own people on the line.
I think Obama has latched on to the drone program because he gets to show the Republicans he can warmonger and escalate as well as they can, but not have to explain to his base why larger numbers of American soldiers are coming back dead. Again, I don't want to see our people die, but maybe if we had to pay a higher price for our interventions, we wouldn't still be in these useless, wasteful wars after a decade.
As long as taxpayer money flows to the defense industry, and defense industry money flows to lobbyists and PACs, and US casualty numbers are low enough to prevent rioting in the streets, our government will see no reason to stop finding new reasons to fight. Even if they have to completely fabricate justifications (*cough*Iraq*cough*).
