Should India intervene in Afghanistan?

In a matter of national security and position in world matters, helping prop up Afghanistan's new Government is in any strong nation's interest.
For anyone interested in solving a complex problem with so many differing interests this offers a real challenge.
 After all Afghanistan is a country which is in the epicenter of the world's terrorism woes. Chinmaya R. Gharekhan for a change provides some deep insight into the problem and clearly portrays the interests of all the parties involved here. The key points he makes are:

• America has subtly accepted defeat in the war against Afghanistan by negotiating with "moderate" Taliban for power sharing.
• India is handcuffed to performing a limited role given the US-Pak relation which relegates India to a passive spectator role.
• Can India perform a viable role? What will be the new government's role?
• India settles for minor platitudes from the International diplomats and is not assertive in protecting its interests.
• India can involve other countries like Iran, China, Russia to prop up a Government more sympathetic to its needs.

I agree with most of his points, yes this is a logical piece. However what I disagree with is the fact that the writer assumes that India plays the same style of diplomacy. India should be more aggressive in matters involving national security. The dynamics of world politics have changed since 9/11. Relying on archaic bodies like the UN and old world alliances have made little sense. How are other countries handling Islamic terror?

• Russia - handles Chechnya with an iron fist. They have made the remaining world shut up and control the media when it comes to covert operations.
• China - tried the negotiations like India used to, but then quickly realized that the Uighurs like the Chechnyans are violent savages who need to be put down and they did the same.
• Iran - The Shia regime while supporting other Shia militant regimes like Hamas and Iraqi terror groups, have not been sympathetic towards Sunni groups other than some public statements against the West.

India's attitude so far has been one of pussy footing, dilly dallying and flip flopping when it comes to a key threat to national security. Being a democracy with so many parties and interests with so little concern to national security, there needs to be some urgency in ensuring that some control is restored to Afghanistan.
