The failure of European countries to agree on a comprehensive counter-terror strategy that balances civil rights with an urgent, growing need for intelligence gathering is a huge weakness in the continent's fight against ISIS, say U.S. experts. And they say there is no more glaring example than Belgium.
"It's a patchwork of laws on gathering and sharing information on individuals," said a U.S. counter-terrorism official, who wished to remain anonymous. While the official noted that there's no proof that better cooperation would have thwarted Tuesday's attack in Brussels, which killed at least 31 people, it has made cooperation if not difficult then frustrating.
Belgium has among the most stringent laws on privacy rights, said the official. These limits on law enforcement, he added, had made Belgium "essentially a safe haven" for ISIS the past few years.
