The growing numbers of migrants and asylum seekers fleeing turmoil in Africa and the Middle East poses complex challenges for European policymakers still grappling with weak economic growth and fractured national politics. Europe, according to a 2014 report from the International Organization for Migration, is currently the most dangerous destination for irregular migration in the world, and the Mediterranean Sea the world’s most dangerous border crossing. To date, the European Union's collective response to its growing migrant crisis has been ad hoc and, critics charge, more focused on securing the bloc's borders than on protecting the rights of migrants and refugees. With nationalist parties ascendant in many member states and concerns about Islamic terrorism looming large across the continent, it remains unclear if political headwinds will facilitate a new climate of immigration reform.
