Why are you making posts here with links, then asking me? The answer is in the link you posted, trying to boost your stance pointing at what Obama did, when it actually proved otherwise.
“The acknowledgement came in a letter signed by U.S. Attorney General Eric Holder sent that day to the Senate Judiciary Committee chairman:
Since 2009, the United States, in the conduct of U.S. counterterrorism operations against al-Qa’ida and its associated forces outside of areas of active hostilities, has specifically targeted and killed one U.S. citizen, Anwar al-Aulaqi. The United States is further aware of three other U.S. citizens who have been killed in such U.S. counterterrorism operations over that same time period: Samir Khan, ‘Abd al-Rahman Anwar al-Aulaqi, and Jude Kenan Mohammed. These individuals were not specifically targeted by the United States.”
And there is a distinct difference between targeting someone, and someone being in harm’s way, being collateral in a place they shouldn’t be in the first place.
