How the Brussels attacks could destabilize Europe
(excerpt)
Countries react very differently to attacks like this. The Madrid attacks in 2004 toppled the government, ending Spanish involvement in the Iraq war. The July 7, 2005 attacks in London, meanwhile, had a negligible impact on the mainstream political system although a very real effect, albeit limited, on community cohesion.
The attacks in Belgium, however, take place against a much wider backdrop not just the Paris attacks but the wider European migrant crisis. Even if all of the plotters in this case turn out to be homegrown, the attacks will still be seen in the wider European context of a continent already struggling to adapt to hundreds of thousands of new arrivals.
The real risk now is that hardliners on both sides end up playing off each other to destabilize the situation further. Already, hardline anti-migrant parties like Alternative for Deutschland fresh from dramatic gains in local German elections earlier this month say the Brussels attacks demonstrate a clear and urgent need to halt new arrivals. Muslim populations in Europe, both established and new, will inevitably find themselves under more suspicion and scrutiny, not to mention facing potential retaliatory violence.
