Upon his release, Vanunu said he was proud of his actions and condemned his treatment in prison, where he spent more than 11 years in solitary confinement. He called on Israel to open up the Diamona nuclear reactor to international inspections, saying Israel has no need for nuclear weapons.
Fearing that he would reveal further secrets, the Israeli government placed severe restrictions on Vanunu following his release, forbidding him from leaving the country, restricting his movements within Israel, and limiting his foreign contacts. Vanunu said he had no more secrets to reveal.
