I don't think you are wrong there. ISIL's branch in Libya rounded up and beheaded about 30 Egyptian Christians and others at the coast. They like to do things as done 1400 years ago. Not much tolerance for anyone, including moderate Sunnis!
and if we rewind to the time when West decided to intervene and support rebels in Lybia, has anyone heard about ISIL in lybia back then? or millions of refugees trying to flee to europe?
i think the pattern is quite clear here:
1) Lybia. Uprisings started inspired by western countries. When the government crushes them, west intervenes and support the rebels. Government is overthrown, country is in chaos, lots of people are killed or become refugees. Radical islamists gain a foothold, acquire weapons, military training and source of recruits.
2) Egypt. Uprisings started inspired by western countries. When the government crushes them, west intervenes and support the rebels. Government is overthrown, radical islamists come to power via elections (!). People get sick of it and army intervenes, ousting the elected government.
3) Syria. Uprisings started inspired by western countries. When the government crushes them, west intervenes and support the rebels. Civil war starts, radical islamists capture significant chunks of the country with support from the west and sunni gulf states. They get weapons, source of recruits, funding from selling the oil, they even get trained in military camps in Jordan, by USA instructors. Millions of refugees.
4) Iraq. USA decides to overthrow Saddam. A secular state, which once was one of the most educated arab countries, becomes an arena for a fight between different muslim factions. All the things that Saddam was accused of still continue, now under democratic banner. Iraq becomes a breeding ground for various terrorist groups.
5) Bahrain. Uprising started but were quickly crushed by Saudi army, that was asked to help by bahrain government. As they are both western allies, no support from the west came to rebels.
6) Yemen. Uprising happened supported by western countries. A new president was elected but then another uprising happened. As the second uprising wasn't sanctioned by western countries, a coalition of gulf countries started bombing the rebels upon request of the ousted president.
7) Ukraine. Opposition, supported by western countries and radical nationalists staged the protests which ended in a coup and the elected government overthrown. The tensions escalated to a civil war and a country sliding into nazi dictatorship. memebers of opposition are now being jailed and/or killed for speaking against the government, journalists killed, head of police and secret services openly saying that anyone with a different view should shut up or risk being killed. there is even a website where they collate personal details of all who speak against government and suggest that those people should be killed. the website is promoted by an advisor to police chief even though it's against the law to publish personal details.
again, millions of refugees and displaced people, and the country is falling apart.
as you can see, every time western countries intervene somewhere, they make it worse.
