I agree with Roosh that the government response will be predictable, but what I'm waiting to see is the response within muslim communities within Brussels. In Paris the attackers went far away from their 'home turf' to carry out their attacks. Here, the muslim areas are very close to where the attacks were carried out. It will be a good barometer to see if the the communities maintain the status quo, or are celebrating in the streets come nightfall (by celebrate I mean, montreal hockey riot style). If there is open celebration it will mean that they know they are winning and are starting to step out into the open.
