Libyan rebels are gaining momentum over loyalists in the revolution. President Obama, after weeks of bloodshed, tacitly lent U.S. support for NATO bombing raids and air attacks on Gadhafi's forces and various government strongholds in Tripoli and other cities throughout Libya.
Pundits and politicians alike have criticized the President for his delay in reacting to the slaughter of Libyan citizens by their own government. The President had methodically hesitated until there was sufficient rhetoric regarding the carnage, and then joined NATO in support of the rebels.
Many of the "rebels" are in fact al Qaeda fighters (some are from the wars in Iraq and Afghanistan and a few had been detained at Gitmo), and when the government is defeated and the revolutionary leaders are placed in power, they will install Sharia as the principal law in Libya (re: Iran, 1979). Sharia is diametrically opposite of democracy.
Obama is fully aware of the rebels' intent.
