Most of us can agree here that in order to preserve western culture, we cannot allow droves of muslims to enter our countries and try to change our rules, laws, cultures and customs. IMO, they are welcomed if they assimilate and contribute, like decades of immigrants did. If not, stay in the middle east.
Your right, if we keep our efforts up in protecting our own countries (and eventually eliminate our oil dependence), we could spend less time meddling in middle eastern affairs...or at least we can try to help them at a safer distance.
