Why were they not booted out of Belgium as criminals?
Because the El Bakraoui brothers were both born in Brussels. The eldest was recently deported from Turkey back to Belgium. Turkey warned Belgium authorities that he was a militant, but Belgium released him as they couldn’t link him to acts of terrorism.
Ever observe the farming practices of the followers of Islam? For centuries the people living on land that was useless sold it to Israelis after the Balfour decision. In twenty years the Israelis turned it into highly productive agricultural land. They applied modern agricultural methods of farming, ran irrigation lines, electricity, access roads, crop storage facilities, and developed markets for the produce. It was now that arabs who sold the land demanded it back! After selling it and finding out what it could have been for 600 years and did nothing with it, now they want it back?
Typical Arab mentality. Scratch the dirt with a stick to farm and steal what you can't produce for yourself.
