Technically, he has not lied... yet. Until the Marines are on the ground, he has not lied.
Of course, not that the majority of the hostilities are likely over, he can claim they are peace keepers, there to assist the new regime, etc., and technically still not have lied.
EDIT:
That was back in March, btw...
Lejeune Marines prepare to deploy off Libyan coast | abc11.com
The 22nd Marine Expeditionary Unit was set to deploy to the Mediterranean later this year but that got bumped up once NATO forces launched an air assault on Libya.
The unit is relieving the 26th MEU, which took part in some of the initial assaults. The 22nd is a Marine, air and ground task force. Some are trained for aviation combat, others for ground combat. They can handle evacuations and humanitarian missions too.
They were already schedule to deploy. It just got bumped up, as a precaution most likely.
Sorry, but nothing to see here folks (and remember, I'm a Republican, a conservative, and I don't like most of what Obama has done to this country).
