In the perspective of what has just happened I think it is time now that India tackled this menace proactively. We have to now to learn from Israel and follow its methods. After the slaughter of its athletes in the Munich Olympics, Israel constituted a team to eliminate each and everyone of the terrorists involved directly or indirectly. This has now been made into a beautiful film by Steven Spielberg titled 'Munich'. And the rescue of the hostages at Entebbe Airport still remains one of the most successful efforts in countering terrorism. And look at Israel today. Even though it is the enemy number one of the Islamic fundamentalists it has been successful in staving off major terrorist attacks on its soil. Why? Because no attack on it is allowed to go unpunished. The USA too has been able to prevent terrorist attacks on its soil. This has to be attributed in part to its excellent defensive measures. However, one has to take cognizance of its offensive measures too.
So it is time that the Government of India constituted a team to go and seek the masterminds and funders of the Mumbai attack and any subsequent attacks and eliminate them, even if it means violating the sovereignty of Pakistan or Bangladesh or any other country, even if it means eliminating General Musharraf or the top brass of the Pakistani Army, who might very well be behind the attack on Mumbai.
Also, I think that it is of utmost importance to start a global movement against terror emanating from Pakistan. India should go about convincing the powers that be in the world that enough is enough. The US and its Coalition has given the government of Pakistan enough time and resources to stop the breeding of terrorism from its soil but with no results. Now, it is time for intervention by a body constituted from agencies/experts of countries like USA, UK, Israel (which might be unacceptable to Islamic nations but they have considerable expertise in countering terrorism) India and Pakistan. This body would be stationed in Pakistan and the Pakistani Government should be made to co-operate; it is hardly in any financial position to refuse.
