An end to America's longest running war isn't getting any closer. The antagonism between the United States and Pakistan — the two most consequential foreign actors in Afghanistan — continues to grow. On Jan. 1, U.S. President Donald Trump fired off his first tweet of 2018, saying that the United States has received nothing but "lies & deceit" in return for the over $33 billion in aid it has provided to Pakistan over the past 16 years. Later that day, the White House announced it would continue withholding $255 million in foreign military financing that had been designated for Pakistan in 2016, but not delivered. Both the tweet and the withheld funding are designed to punish Pakistan for its behavior in Afghanistan, where the United States has now been at war longer than anywhere else in its history.
