EU unhinged: Thursday’s summit faces 2 of its biggest crises

European Union chief Donald Tusk is making clear that the bloc’s 28 leaders are heading into a summit this week that could fundamentally alter the political course of the continent

To listen to harried European Union chief Donald Tusk is to realize that the leaders of the 28 member nations are facing the prospect of an unhinged EU if this week’s summit goes badly wrong.

Negotiations with Britain over EU reforms to give Prime Minister David Cameron a better shot at winning a referendum to stay an EU member are far from finished as they head into the final stretch.

At the same time, the migrant crisis is quickly turning into a seminal test of unity, pitting east against west and many against Greece.
