Military Escalation: "Phase Two" of the War on Libya by Prof. Michel Chossudovsky http://www.globalresearch.ca/index.php?context=va&aid=25081

As part of a "Shock and Awe" strategy, bunker buster BLU 109 2000 pounds bombs are to be dropped on Libya using Britain's RAF tornado fighter jets. Shock and Awe is part of the "doctrine of rapid dominance" or "decisive force", used to intimidate the adversary into submission, as well terrify the civilian population. 

It is worth noting that the use of Shock and Awe tactical nuclear weapons against Libya has been contemplated as part of this "humanitarian war". In 1996, Libya was the "chosen country" in the Middle East and North Africa to be targeted with a B61-11 tactical nuclear weapon. The latter is a bunker buster bomb equipped with a nuclear warhead.

The plan to nuke Libya was never scrapped. Of utmost significance, shortly after the commencement of the bombing campaign on March 19, the Pentagon ordered the testing of the functionality of B61-11 nuclear bomb. These tests were conducted using the same B2 Stealth Bombers, out of the same US military base in Missouri, which were used to coordinate the B2 Stealth bombing raids on Libya at the outset of the war on March 19.
