What he's done with the drone war could be considered terrorism. He's unapologetically murdered innocent civilians with a falsely labeled "precise" attacks and left thousands of innocents in fear for their lives on a daily bases. This of course has strengthened support for extremist regimes. I don't think you can say that "boots on the ground" is a worse solution. Maybe for our convenience it is, but it doesn't seem to helping any sort of cause, and it puts foreign innocents at risks over our soldiers.
Arguing Obama's war policies is probably not a road supporters should take.
Foreign innocents are just as much at risk when our troops are there shooting around.
I brought this up a couple weeks ago in this thread and I don't remember if you were around for it...but I'd really prefer we just start going hardcore covert assassin mode at this point. Find a target, send in a sniper team, take him out. Invading entire nations and drone attacking targets just leads to more innocent deaths which leads to more people getting pissed off.
I know cold blooded assassination isn't exactly a great thing to do, but hte fact is America does have enemies, and those enemies need to be dealt with somehow. I think the best way to do so is take out the ones that currently exist while avoiding, as much as possible, taking innocent lives in the process.
