The last 50 yrs has shown us that Pakistan perpetually moves from a facade of democracy to a military rule.
It just cannot move permanently away from military because of their constitution and people at large.
In this background, it is debatable whether Mr. Vajpayee's initiative of talks with pak, with the associated expenses, time, almost zero yield, continuing of terror attacks (recently there was an attack on Mr. Nabi azad), was worthwhile.
A more pragmatic approach of sealing of borders, stringent measures to prevent terrorist attacks, is recommended.
Notice that as it is becoming increasingly difficult to conduct attacks in US, terrorists are now on UK.
While Paks dream of raising banner in Delhi is downright hilarious, India's quest for peace with Pak is no less.
