^^ true.
Militants from one sect got money from Arab "charities",
and
Militants from the other sect got money from Iranian "charity".
The obvious result was a long chain of attacks on each others' mosques, madrassahs, and militant leadership.
Iranian supported militants have "thankfully" stopped their heinous work in most of the places.
Unfortunately
Arab supported militants do not know how to stop until they are bludgeoned by our law enforcement agencies.
The blame for all this mess goes squarely on our "zealotry and Islamist religiosity" that makes us forget that Pakistan's borders must be cherished and protected if we ever want to have a decent life.
