There is a strong growing awareness that measures have to be taken to check these forces, Singh said.

Gen Mike Mullen, Chairman of Joint Chiefs of Staff of the US,  has said that there are "certain forces in Pakistan. It is not new to us. If fact, the world did not believe us earlier. I am quite certain that now the world will wake up to these forces."
