Perhaps if we stopped getting involved in conflicts that have little if anything to do with us, there wouldn't so much destabilisation in these countries that end up with us having to take so many asylum seekers.
I agree that short-term focus on places from where radicalisations grow needs to happen, the question is, how? How do we know what the most effective way to do that is? I think it'd be naive to think that wouldn't just push the problem even more underground.
