Well, first off, your supposed "liberal" governments took Ghadaffi out of power in the first place, claiming he was a terrorist himself. Now these countries are in turmoil because of your "liberal love". Secondly, please address the article for what it is, giving jobs and funding to ISIS combat vets. I think deep down, you agree with that notion because you're Keynesian. Once again, I've asked this twenty times now, where do you get the funding for that?
First of all, ISIS developed primarily in Iraq and Syria and is now expanding to Lybia, the military actions against Ghadaffi and his death had relatively little to do with it compared to other issues in the neighbouring countries, in the short term. Especially as Libya was basically in a civil war by the time the air strikes took place, and even if Ghadaffi would probably have solidified his position in the long run his regime wouldn't have had the resources to additionally fight ISIS.
Secondly, there's a lot to critisize about the military involvement in Libya, and I honestly don't know enough to say whether it was the right decision, but most judgements nowadays rely heavily on the benifit of hindsight. Without the interventions, chances are that it would've panned out similar to Syria as well, not much of an improvement over the present situation. And there def Of course there's also the question of the real reasons behind the intervention (oil, commercial interests, etc.).
Thirdly, I don't see where this article talks about "giving jobs and funding to ISIS combat vets". It just says that as long as the overall economy is fucked and people, especially young people don't have any opportunities there will be a large number of people seeking refuge in militant religious philophophies and groups such as ISIS. Therefore, if the US are interested in combating ISIS in the long run, there need to be better prospects for the population there.
Also, there's no mention anywhere of Keynesian methods or the creation of jobs and improving the economic situation trough large scale government intervention. It just says "We can help them build their economies so they can have job opportunities for these people.” I mean if you want to say that government intervention is the only way to create jobs and build an economy, that's fine, but I don't think that's what you mean

But in theory building an economy can just as easily mean by other economic doctrines, be it neo-liberalism, monterianism, socialism, whatever.
