There is no record of a hostility between the Baluch and Hazara.

I unconditionally condemn the violence against the Hazara people in Quetta especially double bombing of the Hazara club in Quetta. The Hazara people are one of the most suppressed people in the Afghanistan. http://www.myweather2.com/City-Town/Afghanistan/Bamiyan/map.aspx

The Hazar people have their own homeland in Bamyan Afghanistan. There are also indigenous Hazara communities in Mashhad Iran.  http://en.wikipedia.org/wiki/Mashhad

The Hazara people had migrated to Baluchistan when Abdurrahman the king of Afghanistan became hostile toward Hazara community. The Baluch communities have never been hostile to the Hazara community in Quetta or anywhere else. The Hazara and Hindu communities have always been protected by the Baluch communities in Baluchistan.

There is no record of hostility between the Baluch and Hazara.  The Pakistan has become a failed state. The   religious sectarian and ethnics conflicts will be boosted, the historical hatred will be revitalized and the Hazara people are well aware of their historical enemies.

Now Pakistan army has imposed the wars on Baluch, the Baluch properties, children, young and old are not safe in their own homes. The Baluch has lost power to protect itself therefore the Hazara, and Hindu have always been hated by religious fundamentalists also not safe. The violence against Hazara and Hindu imported from Punjab, karachi Islamic schools founded by Arab petrodollar.

The Taliban, lashkar-e- Jangavi and so forth are parts of Pakistani army but in civilian uniform. The F, C is commanded by serving army offices. The good Taliban, bad Taliban and Lashkar-e-Jangavi are commanded by the Pakistan intelligences officers. 

If the Pakistan army had protected the Hazara in Quetta the Hazara genocide would not has happened.  The Baluch has been arguing that the Pakistan army is a jihadi army.

One would wishes that The Hazara people stop a fantasy in believing that the Pakistan army will protect them from its own trained killers that will not happen. The only way forward for the Hazara people is to build bridges between communities, after all the communities have been protecting the Hazara people in Baluchistan. The Pakistan army cannot protect itself from hostile communities.
