Pakistan's post-coup government is wildly unpopular with all the Pakistanis I know here, mostly for its open ties to the CIA. Don't imagine that goes down any better at home. Given the political situation, Pakistan's military might capture Zahedan only to lose Karachi and Islamabad.
And the Baloch Islamists who were hit are at best frenemies of Pakistan's military, and then only as long as they're being paid.
Nothing will happen. It will be forgotten in a month.
