Chancellor Angela Merkel made a forceful pitch for Europe to play a more assertive role in global affairs as U.S. President Donald Trump dismantles the post-World War II order, setting the stage for a potential tense standoff at the Group of Seven summit this week.

The German leader again questioned the durability of trans-Atlantic relations by referring to eye-raising comments she made over a year ago in which she said that “the times when we could fully rely on others are to some extent over.” Those words, spoken at a beer-tent election rally, were a reaction to Trump hectoring European leaders for not spending enough on defense at a North Atlantic Treaty Organization summit in Brussels. Since then, more fuel has been added to the fire.
