• North Korea’s nuclear threats, combined with President Trump’s unpredictable foreign policy, are fueling a national debate in Australia about the country’s relationship with the world.

On Monday, Mr. Trump said he would be “honored” to meet with the North’s leader, Kim Jong-un, “under the right circumstances.”

Australia is essentially caught between China, its largest trading partner, and the U.S., its most powerful ally. President Trump and Prime Minister Malcolm Turnbull meet for the first time this week, on an aircraft carrier in New York.
