New Delhi: Attributing the Myanmar operation to a "change in mindset", Defence Minister Manohar Parrikar today took a dig at Pakistan, saying those who "fear India's new posture" have already started reacting.

"If the thinking pattern changes, lot of things change. You have seen what happened in the last few days. A simple action against insurgents has changed the mindset of the full security scenario in the country," he said, addressing a seminar on Thursday.

Khan's statement came in response to Minister of State for Information and Broadcasting Rajyavardhan Singh Rathore's remarks that military action in Myanmar to hit back at rebels who killed 18 soldiers in Manipur was a message to other countries.

Rathore's comments were interpreted here as a warning to Pakistan.
