Attitudes toward the United States are improving across the Atlantic—but only because the right wing is getting stronger.

Over the last year, European anti-Americanism has ebbed somewhat, thanks in large part to the sentiments of right-wing populists enamored with U.S. President Donald Trump. Their fond feelings have created a surprising opportunity for Washington to repair the trans-Atlantic relationship that it has recently done so much to dismantle.

If there is one unifying sentiment among supporters of the Alternative for Germany (AfD), Italy’s Lega Nord, the Sweden Democrats, the National Rally in France, and the UK Independence Party (UKIP), it is that they all increasingly approve of Trump. That’s rooted in the extreme right’s soft spot for authoritarians and Trump’s own anti-immigrant stance.
