As Christopher Hitchens so ably pointed out, the problem with non-interventionists is that they often fail to account for the fact that in the absence of U.S. action, it's not that "nothing" happens. It is that something else happens.
Without U.S. intervention, Libya would look like Syria, not Saudi Arabia.
take the point about not intervening doesn't prelude "something else" from happening.
We know what happened because of Libyan war, there isn't a lot of good that came from it - I'd argue there was a lot of bad things that did come from it.
Libya today is in very bad shape, this is a direct result of our intervention.
One has to own this idea that the west destabilized a fairly stable country ( if despotic rule), allowed the rise of the militias, Bengazi,
and assorted jihadist we assisted were already trained in Iraq.

LIBYAN JIHADISM BEFORE THE WAR
Prior to the 2011 uprising, the country's main organized jihadist movement, the Libyan Islamic Fighting Group, had already deradicalized and retired. Founded after the anti-Soviet jihad, the LIFG attempted to overthrow the Qadhafi regime in the mid-1990s but began to move away from armed conflict in 2006.
In 2009, the group's shura council members -- some in Libyan prison, others in exile in Europe -- negotiated an end to conflict with the regime via Qadhafi's son Saif al-Islam.
The minority that disagreed with that decision joined al-Qaeda in Pakistan, leaving no organized presence in Libya.
Therefore, on the eve of last year's war, organized violent jihadism in Libya was more or less extinct
In addition, Libya has become a transfer point for fighters from Western Europe and the Maghreb headed to Syria. News reports and jihadist sources suggest that some of these individuals have attended training camps in Misratah, Benghazi, the desert area near Hon, and Green Mountain in the east, though the accuracy of these reports is unknown
