(CBS News) — Sen. John McCain continued to press President Barack Obama for a more forceful strategy to remove Muammar Qaddafi from power in Libya, saying that the U.S. should be willing to use “any means” necessary to accomplish that goal and comparing the current strategy of limited air power combined with diplomatic pressure to the post-Gulf War strategy in Iraq that kept Saddam Hussein in power.

Mr. Obama laid out his case for intervention Monday night, saying that he authorized the use of missile and airstrikes in an international military action to protect civilians from a “massacre.”

However, while the U.S. policy calls for the departure of Qaddafi from power, the president said the U.S. would not be willing to pursue deeper military involvement, such as sending in ground troops, to make that happen.

Instead, the U.S. would support the continued coalition-led no-fly zone in addition to economic sanctions and other diplomatic tools to increase pressure on Qaddafi.
