A vicious circle of reprisals and hostility

From this week’s Economist leader. I suspect they’re underestimating the extent to which Trump will largely enact the Ryan-ist mainstream in economic policy. However they’re surely correct about the underlying dynamic: Trump’s policies intensifying the conditions which gave rise to him, creating more anger and encouraging the ethno-nationalist channeling of that anger as a political survival mechanism:

Mr Trump needs to realise that his policies will unfold in the context of other countries’ jealous nationalism. Disengaging will not cut America off from the world so much as leave it vulnerable to the turmoil and strife that the new nationalism engenders. As global politics is poisoned, America will be impoverished and its own anger will grow, which risks trapping Mr Trump in a vicious circle of reprisals and hostility. It is not too late for him to abandon his dark vision. For the sake of his country and the world he urgently needs to reclaim the enlightened patriotism of the presidents who went before him.
