Israel's science minister Gila Gamliel says a window of opportunity has opened to oust the Islamic Republic and replace it with a new government following the recent Israeli airstrikes against Iran's military assets and the weakening of its allies.

"After we severely damaged the arms of the Iranian octopus, and it is at its weakest following the damage to the missile array and air defense - a window of opportunity has opened to overthrow the regime," Gamliel said.

"Now is the time to act together with the free world to replace the Iranian regime," she added in a post on her X account.
