In the Kayhan newspaper, which is published under the supervision of a representative of the leader of the Islamic Republic, the note reads: "Changing the nuclear doctrine and, as a result, improving deterrence may prevent the risk to the system and the territorial sovereignty of the country." This newspaper added: "If the Islamic Republic had nuclear weapons, its leader would not have been attacked and assassinated like this." Keehan added: "In the tensions between India and Pakistan, the possibility that the parties will use nuclear weapons is a deterrent, and in North Korea the direct attack of the US is actually avoided as a deterrent, and the approval of this country's decisive nuclear response in the event of an attempt to assassinate its leader is a strong guarantee against any kind of deterrent error barrier."
