Amid the world’s worst migrant crisis on record, the Trump administration is cutting back on refugee resettlement. As part of his travel ban, President Trump capped the number of refugees to be admitted in 2017 at 50,000, the lowest number in decades. Now the administration has proposed lowering the goal even further, to 45,000, next year.

Over the years, the United States has lived up to its ideals and brought millions of refugees to safety and freedom. It didn’t become a resettlement leader out of pure altruism. By welcoming refugees, the United States revitalizes its democracy and its economy, helps preserve or restore stability in volatile regions of the world, and builds respect.

In slashing resettlement, the president is taking a recklessly narrow view of how best to put America first. Shutting out refugees would not only increase human suffering; it would also weaken the country and undermine its foreign policy.

There are more than 22 million refugees in the world, the highest number since World War II. Even before the Trump presidency, the United States response to this crisis was relatively modest. In fiscal year 2016, the United States resettled about 84,000 refugees, the most of any year under President Barack Obama. For comparison’s sake, the country took in roughly 200,000 refugees a year in the early 1980s under President Ronald Reagan.
