Ignatius: NATO Article 5 nearly dead, US blind to Russia's hybrid war

Influential commentator David Ignatius, writing in Foreign Policy, argues that the US administration is largely unaware of the scale of Russia's hybrid attacks in Europe and Moscow's true intentions. He warns that NATO's Article 5 collective defence clause has become "almost a dead letter". Ignatius calls for renewed US engagement with the EU and NATO to avert a strategic catastrophe.
