Bloomberg Opinion on a refugee crisis created by Pakistan (Dec. 11):

Amid wars in the Middle East and Ukraine, Western governments have limited capacity to deal with another humanitarian crisis. Yet a decision by Pakistan to expel hundreds of thousands of Afghans threatens to create a new wave of refugees and destabilize an already volatile region. Preventing the chaos from spreading needs to be a priority for the U.S. and its partners.

In October, Pakistan’s caretaker government announced that all foreigners residing in the country without legal documents would have to leave by Nov. 1. Pakistan hosts more than 3 million refugees and migrants from neighboring Afghanistan, including roughly 600,000 who fled after the Taliban regained power in August 2021. About 1.7 million of them were believed to lack proper papers when the expulsion order was issued. Since then, more than 400,000 have crossed into Afghanistan.

Pakistan says its decree doesn’t target Afghans specifically. But some officials have linked the policy to a recent upsurge in attacks by militants, including Afghans, affiliated with a terrorist group called Tehreek-e-taliban Pakistan, or TTP. Pakistani officials accuse Afghanistan’s Taliban rulers of providing the TTP’S commanders with havens from which to mount attacks against Pakistan. After trying various means to pressure the Kabul regime, including by raising fees on Afghan goods exported through Pakistani ports and even conducting cross-border airstrikes targeting TTP fighters, Pakistan now appears to be exploiting the migrants as leverage.

The vast majority of Afghans being expelled have nothing to do with the TTP. Many have lived in Pakistan for years and are returning to a country they barely know. Others worked with NATO forces and are waiting in Pakistan for their visas to the U.S. or other countries to be processed. As they’re pushed out, migrants have reportedly been stripped of their money and belongings. According to Human Rights Watch, some have been beaten, threatened with sexual assault or had their homes bulldozed.

In addition to the humanitarian toll, the exodus poses potential security risks. Afghanistan is already facing a dire economic crisis, with two-thirds of the population dependent on outside assistance. Refugees who can’t provide for their families may well attempt to migrate again, perhaps to Turkey and onward to Europe, exacerbating the West’s migration challenges. More likely, they’ll sink deeper into poverty and despair, fueling radicalization and providing terrorist groups such as the TTP, Islamic State and al-qaida with new recruits.

For those reasons, the outside world can’t afford to look away. The Biden administration should pressure Pakistan either to reverse its policy or at least delay its implementation until after the harsh winter months, giving both migrants and Afghan officials more time to prepare. Pakistani officials should work with the United Nations to ensure anyone with a credible fear of persecution is not forced back. Afghans who have established some legal status in Pakistan should be given amnesty from deportation.

In return for Pakistan’s agreement to halt expulsions, the U.S. should share intelligence to help the government locate TTP leaders. Pakistan has a right to address legitimate security concerns. What it should not do is force innocent Afghans, who have seen too much suffering already, to pay the price.
