Combating terrorism- Is this simply state's moral duty?

Chidambaram's advice to Pakistan is very bizarre. He says that fighting terrorism is 'moral' duty.

Everyoneknows that defence of boundaries and citizens from internal and external forces is 'statutory and binding' duty of every government. It is binding and statutory duty of Pakistan to fight terrorism and not allow any Anti Indian activities and terrorist act from their soil. If this is simply moral duty, Pakistan id under no compulsion to accept the advice to perform 'moral duty'.

It appears that the UPA leaders similarly do not consider that they have any binding duties towards people. Even fighting corruption, inflation, terrorists are simply 'moral duty'.
