After 14 years of utter failure in Afghanistan and Iraq post 9/11, and so many more before that, I kinda want to try out the idea of getting the feck out of the Middle East, Afghanistan, North/East Africa AND Israel. Maybe it's time to let them deal with their own mess. Let whoever want to emigrate from the West and go and fight do that. Spend the money saved on finding an alternative to oil and save the planet along the way.
It might sound a bit harsh based on the concept of humanitarian intervention, protection of minorities etc (which I believe in). But no one really gave a shit about Taliban's ISIL'esque mass executions of Afghanistan's minorities and extermination of whole villages in the late 90s. Rohingyas in Burma, genocidal tendencies in the Central African Republic, Darfur, Congo, the list goes on.
An intervention must be massive, probably a million plus soldiers, and everyone have to be willing to look at it as a 50-year project at least. I'm still not sure it would work out great even if you had some Gandhi'esque leader to take charge and unite everyone.
