No he's not. He's making it clear that the community itself is also involved in sectarian violence. They are not the completely innocent party they claim to be. In the media and the public, their ethnic and religious leaders cry bloody murder yet the same leaders actively support and at the very least turna blind eye to their own kin commiting sectarian acts of violence. Maybe they should sit in the roads and protest that the hazara terrorists from amongst themselves also come back home and stop commiting terrorism in Syria?
In his statement he has clearly said that innocent people are killed in Pakistan because of sectarian violence, for years that has predominantly been shia victims of wahhabi groups. The security force will come as a great relief to a community which is being targetted but at the same time, the long term solution for this is multi pronged. Other people have mentioned larger operations, more intelligence involvement, and
@Maarkhoor mentioned the involvement some hazara people have in sectarian conflict abroad. It is just as legitimate a security requirement as stopping groups like IS or anyone else who operates outside the writ of the Pakistani state.
