We should not be emotionally charged on this, first we need irrefutable evidence. If it is established as a fact beyond doubt that India carried out the slaughter of our kids, then the evidence must be shared with every section of the political, military and civilian establishments.
Then we establish a new service with a 20 year mendate, with independent off the grid operations and funding from the narcotics ceased from Afghan smugglers so there's no paper trail, its sole objective should be to finance, plan and execute an industrial scale murder of Indian civilians, and families, parents and children of those from Indian secret servics who executed and planned this massacre.
If and its a very big if, this is done by India, we want blood in return of both guilty and innocent Indians, and nothing less.
