Drones Are Legal?

Once agin a drone plane operated by someone in Virginia–USA, that is–hovered over a compound in North Waziristan, Pakistan, then fired some missiles, and within moments at least nine people were dead. Based on an interview with the drone, it informed us that US military guidelines make certain that whenever it fires a missile, the target must be a Muslim militant. It is against regulations to kill innocent people, and we know how drones regard such actions to be illegal.

President Barack Obama, former professor of law and international relations insists that any country can send a plane into another nation if it believes there are bad people in that location who must be killed. I am not an expert on international law, but something tells me this is illegal.

I am confused as to why Mitt Romney is in favor of drone attacks, I thought he opposed any and all ideas of Barack Obama!
