They are even closing the border to prevent people escapes. Shame.
Pakistan was never really good US ally. During the Cold war, India was SU ally, so naturally US supported Pakistan.
Since the collapse of SU, India became more of an ally of the US. Especially Pres. Trump was heavily courting India, so Pakistan became even less of an ally.
BTW, Pakistan is such a screwed country! Kind of a volcano of hundreds of different interests.
The only common denominator is Sunni Muslim faith. Not exactly the best nation building glue.
India and Pakistan used to be part of the same country. Another botched partitioning effort by the British (just like their Middle East disaster).
