That is up for debate.
The previous government was unable to deliver results with-respect-to Pakistan, so when the result is negative, that automatically puts the methods they used as wrong.
This Government is trying a different approach. Let us see whether it yields results or not. They have 5 years to show results.
Government decisions are not adhoc. They have career bureaucrats, intelligence chiefs and army chiefs brief them when taking national policy decisions. And I can say for sure that the National Security Advisor to the current Govt - Mr Doval is far more competent than the last NSA.
I would say it otherwise, actually the world was forgetting about Kashmir issue and in last 5 or so years after Kargiil it wasn't much in the news. Showing more bravado doesn't mean competence.
