Since setting out his plan for Afghan escalation, President Trump has repeatedly criticized Pakistan for not doing enough to support the US war. On Monday, Trump accused Pakistan of having played the US for fools in the course of foreign aid, getting $33 billion for "nothing."
Trump pledged to stop aid to Pakistan, pending a review of their "level of cooperation." Absent in this, as with most cuts in funds to Pakistan, is that many of the US payments to Pakistan are intended as payments for services rendered by the Pakistani government in the course of the Afghan War.
Pakistan has been increasingly annoyed by Trump's criticism for months, and was quick to fire back after this most recent comment, saying all the US ever offers is "invective and mistrust," despite all of Pakistan's intelligence cooperation and use of land and air communications.
