However there is one interesting continuation from the Bush era; the authority to kill US citizens abroad. This should obviously present many legal and ethical issues for any administration but at present the threshold seems to be set at if the person "a continuing and imminent threat to U.S. persons and interests". Is a US citizen chooses to join an organisation such as A Qaeda then "they are then part of the enemy".
For now there seems to have been little debate as to the continuation of this policy, or even its existence I expect in many cases. Though for an organisation like Al Qaeda it would be interesting to see if their propaganda machine could start to use this against the US or on the flip-side when would the US consider it acceptable to target a US citizen who was not abroad?
More can be found at the Washington Post below.
a U.S. citizen, Anwar al-Aulaqi, was thought to be meeting with other regional al-Qaeda leaders. Although he was not the focus of the strike and was not killed, he has since been added to a shortlist of U.S. citizens specifically targeted for killing or capture by the JSOC, military officials said.
he has embraced the notion that the most effective way to kill or capture members of al-Qaeda and its affiliates is to work closely with foreign partners, including those that have feeble democracies, shoddy human rights records and weak accountability over the vast sums of money Washington is giving them to win their continued participation in these efforts.
