Four months into the NATO air campaign, Col. Muammar Gaddafi is still in power, protected by loyalists and mercenaries. Americans are weary of war, and patience in Europe is also wearing thin. But NATO must not give up. If Colonel Gaddafi is allowed to have his way, thousands more Libyans will die. The credibility of NATO and the US would also be severely damaged. Colonel Gaddafi, who has a long history of sponsoring international terrorism, is not one to let bygones be bygones, writes The New York Times in its editorial. Excerpts: There is progress. The make-shift rebel army — aided by British, French and Italian advisers and armed by France and Qatar — is slowly improving. NATO strikes on military command centers, including Colonel Gaddafi's compound in Tripoli, have done real damage. This week's International Criminal Court indictment of Colonel Gaddafi, one of his sons and his intelligence chief on charges of crimes against humanity should be a warning to all of his cronies. A naval blockade and international sanctions are increasingly having an effect. Oil revenues, the government's main income, are down by two-thirds. There are reports of long gasoline lines in Tripoli and rising bread prices. Italy's recent call for a ceasefire (which could give government forces time to regroup) is not helpful. NATO must help, but the Libyan people are the only ones who can bring the regime down. The rebels need more military advisers and weapons and access to $30 billion in frozen Gaddafi government funds. The United States and other countries need to remove the legal obstacles to getting that money. The alliance should extend sanctions to more of Colonel Gaddafi's cronies and the subsidiaries of state-owned enterprises. Washington and its partners should also help the rebels start building the political and civil institutions they will need to keep a post-Gaddafi Libya from descending into chaos. There has been recent talk by all sides about a possible political deal between the rebels and the government. We are eager to see an end to the fighting. But Washington and NATO must stand firmly with the rebels and reject any solution that does not involve the swift ouster of Colonel Gaddafi and real freedom for Libyans. __
