"The answer is to increase cooperation between the two countries, and to deal with the problems more proactively"

I'm someone who believes that the Mumbai attack was intended to derail Zardari's Peace feelers to India. Here's Anwar Sher on PostGlobal:

"The killing of any human being is not something one should gloat over, justify or otherwise praise, and in this vein the attacks in Mumbai are horrific to say the least. It would also seem, based on evidence so far, that some militant groups based in Pakistan carried out this attack, and Pakistan has offered to prosecute these people and some arrests have been made.

While India may suggest that Pakistan is not doing enough, the fact that there has been a state of turmoil within Pakistan for over a decade suggests that reining in these militant groups is not exactly as easy as it sounds. The charge that elements within Pakistan's Directorate for Inter-Services Intelligence (ISI) have had inks to militant groups could well be true -- but is not necessarily proved beyond a shadow of doubt.

I do not think war-mongering or taking a page out of U.S. policy of retaliatory strikes is the answer in this situation.

First of all, Pakistan has its own problems with its home grown terrorist threat, losing a Benazir Bhutto to one such attack, the culprits behind which still remain at large.

Secondly, Pakistan's society is fragmented, and divided, especially in the northwest, where more of the population lives in fear of the next terrorist strike than of the next U.S. missile strike. In this atmosphere of strife, it is easy both for militant groups to operate with relative immunity and for militants wanted by foreign governments to hide.

Thirdly, while this tragic attack against the people of Mumbai was perhaps largely carried out by Pakistani men, one cannot simply say India's entire history with terrorist attacks rests on Pakistan's doorstep, as we would be forgetting that earlier bombing attacks on the Mumbai stock exchange and elsewhere were carried out by India's own home grown brand of terrorists. In 2007, a terrible bombing of a train linking India and Pakistan, in which 63 people were killed mostly Pakistanis, was linked to an Indian group in Indore.

Sensible people on both sides of the border have to accept that terrorism is not a state sponsored act insofar as these two countries are concerned. While Pakistan has not been able to control the groups operating within its own territory for the reasons cited, it would be naive to assume cross border raids will achieve much more than to raise tensions between two countries who can ill afford a war at this stage.

The answer is to increase cooperation between the two countries, and to deal with the problems more proactively, and to create a framework of trust between each nation's secret service organizations. In reality, Pakistan gains little from sponsoring terrorist attacks against others when when its own militants are harassing the country from the inside. We must understand and appreciate that militant attacks of this sort are a problem for both India and Pakistan and that dealing with them by more saber rattling will achieve nothing but tension.

Pakistan must also work harder to clamp down on these groups, which have caused so much damage within and outside the country. It cannot just go on hoping the problem will go away with time. It is important that sanity prevail at moments like. We must find peace at these moments, not more deaths."

I find this a sensible view.
