The U.S. said Monday that it is cutting $1 billion in assistance to Afghanistan this year after the country’s rival leaders failed to agree on an inclusive government.  

In a statement, Secretary of State Mike Pompeo said the failure posed a threat to U.S. national interests and the U.S. government will initiate a review of the scope of its cooperation with Afghanistan.

“Among other steps, we are today announcing a responsible adjustment to our spending in Afghanistan and immediately reducing assistance by $1 billion this year,” said Pompeo. “We are prepared to reduce by another $1 billion in 2021.”
