The world is now finding out about, what appears to be, two huge failures of the Belgium intelligence and security services. And the citizens of Belgium, and all who were killed and injured in the attacks in Brussels, deserve an explanation.
Failure one is that President Erdogan of Turkey warned Belgium that one of the attackers was a militant after Turkey deported him in July 2015.
Failure two is Belgium intelligence and security services had “advance and precise intelligence warnings” regarding the attacks.
The security services knew, with a high degree of certainty, that attacks were planned in the very near future for the airport and, apparently, for the subway as well. Despite the advance warning, the intelligence and security preparedness in Brussels, where most of the European Union agencies are located, was limited in its scope and insufficient for the severity and immediacy of the alert.
