So, how can India protect itself from invaders across its western border and grave injury? Just as importantly, how can we in Pakistan assure that the fight against fanatics is not lost?
Let me make an apparently outrageous proposition: in the coming years, India’s best protection is likely to come from its traditional enemy, the Pakistan Army. Therefore, India ought to now help, not fight, against it.
This may sound preposterous. After all, the two countries have fought three and a half wars over six decades. During periods of excessive tension, they have growled at each other while meaningfully pointing towards their respective nuclear arsenals. And yet, the imperative of mutual survival makes a common defence inevitable. Given the rapidly rising threat within Pakistan, the day for joint actions may not be very far away.
Today Pakistan is bearing the brunt. Its people, government and armed forces are under unrelenting attack. South Waziristan, a war of necessity rather than of choice, will certainly not be the last one. A victory here will not end terrorism, although a stalemate will embolden jihadists in south Punjab, including Lashkar-i-Taiba and Jaish-i-Mohammad. The cancer of religious militancy has spread across Pakistan, and it will take decades to defeat.
