U.S. diplomats' return to Libya could be more hazardous than exit

WASHINGTON (Reuters) - If evacuating U.S. embassy staff from Libya was perilous - three F-16 fighters and Marines in Osprey aircraft flew overhead a road convoy from Tripoli to Tunisia - sending them back in could be politically hazardous for President Barack Obama.

U.S. diplomats work in dangerous places such as Baghdad and Kabul, but the ghosts of Benghazi hang over the U.S. presence in Libya after an attack on a U.S. mission in the eastern Libyan city in 2012 that killed Ambassador Chris Stevens and three other Americans.
