Senator John McCain, who visited Libya at the weekend, also said that the Libyan dictator should be targeted but argued that it was more important to increase American firepower over Libya. He said: "It's pretty obvious to me that the US has got to play a greater role on the air power side. Our Nato allies neither have the assets, nor frankly the will - there's only six countries of the 28 in Nato that are actively engaged in this situation."
