Seems like you have your answer in the last few paragraphs of the article. Amazing!
ABC News is already trying to spin this as something Libya had planned to do all along. They imply at their website that it had nothing to do with Bush's foreign policy, but was just part of Mohmar's attempt to internationalize his country.
What a bunch of crap!
Bush's War on Terror has lead to the capture of Saddam, massive drug confiscations, and this coup in Libya (just in the last week), but they'll never give him credit for it.
Here's the link to the ABC article:

Especially notice these two paragraphs:
"The United States and Britain portrayed the announcement as a significant breakthrough in their efforts to curtail the spread of such weapons and keep them from a terrorist organization or hostile country.
It is clear, however, that Gadhafi has tried in recent years to ease tensions with the West, and this step was expected to further improve Libya's international standing."
....not to mention the complete capitulation of the French and Germans....a good week indeed.
