His remarks came two days after the Centre briefed opposition parties on the stand-off with China and the situation in Jammu and Kashmir in the aftermath of an attack on Amarnath pilgrims.
The former Union home minister said the Kashmir issue is "a festering wound" and the people of the Valley are caught between "two maximalist positions" taken by the central government and militants.
The casualties are the people of Jammu and Kashmir and the future of the state, he said in a series of tweets.
The senior Congress spokesperson posted on Twitter that on many occasions in the past, he had "cautioned that the Kashmir issue or problem (or by whatever name it is called) was a festering wound".
The Opposition has been blaming the Centre and the PDP- BJP government in the state for the unrest and violence in the Kashmir Valley since the death of Hizbul leader Burhan Wani in an encounter with security forces last year.
