Obama And The 'Good Drones'

Beyond that, the administration listed criteria for the approval of a drone strike:

• "Near certainty" the target was present and that civilians would not be injured or killed 
• Capture would not be feasible 
• Authorities of the country in question could not or would not address the threat 
• No other reasonable alternatives were available

On Wednesday, the US disclosed that four Americans had been killed in drone strikes. LINK
