The way it is being pitched is:
The United States and its NATO allies need to step up involvement in the war in Libya. Firing hundreds of Tomahawk cruise missiles and enforcing a no-fly zone with Hornet, Tornado, and Mirage aircraft has only been enough to stop the advance of Gadhafi's forces. It is uncertain what the affect of arming the opposition and utilizing unmanned Predator Drones, armed with Hellfire missiles, will be on the situation, but it will likely require more to reach our end goal.
This either sounds bad-ass or frightening, depending on your side of the debate. If you want to be able to sell the idea that more needs to be done, you need to make it sound friendly. First, war has such a negative connotation. Why not call it a game? Everyone likes games. We're just going to go referee the game to make sure that both sides play fairly and that breaking the rules (such as being a dictator) is penalized. Tomahawks were a weapon used by Native Americans. Native Americans also used peace pipes. Instead of Tomahawk cruise missiles, why don't we call them Peace Pipes? As for the fighter jets, hornets are very aggressive, and no one wants to have hornets around. Why not call them Butterflies? Tornadoes are very destructive. Instead of a tornado, I would rather have a light breeze, so we'll call them that. A mirage isn't even really there, so we'll just stick with that. Giving arms to opposition groups has come back to bite us in the past. Instead of arms, why couldn't we give them another body part? Like hearts? Who would object to us giving them hearts? Predator is also a bad word. Either you think of an animal that hunts and kills things, or you think of a pedophile or rapist. Neither gives you warm, fuzzy thoughts. Why not call them Kittens? Cats are predators, but no one is afraid of a kitten! Hellfire missiles obviously need a new name. Hellfire is definitely not a good thing. However, everyone likes a bonfire, so we'll call them Bonfires.
The new pitch for increased involvement would look something like this:
America and friends need to take a stricter referee role in the freedom game in Libya. Sending hundreds of Peace Pipes and having Butterflies, Light Breezes, and Mirages flying over Libya has resulted in a tie, and we need to ensure that rule infractions are penalized during overtime. It is unsure whether giving the good guys hearts and sending Kittens to light Bonfires for the Libyan people will be an adequate penalty for breaking the "oppression" rule. It is likely that further penalization will be necessary.
Wording his argument like this would certainly enable President Obama to get the majority of Americans behind him, regardless of the level of force he wants to use in Libya.
