Keihan newspaper: nuclear weapons do not prevent war, but if Iran had such a weapon, its leader would not be attacked and assassinated. Kahn wrote: The owners of nuclear weapons each set a final goal for the use of nuclear weapons and approved to the parliament in cases where survival and maintaining territorial sovereignty is at risk, including the commonality between them, which can prevent the expansion of the scope of the war, but in the war between Ukraine and Russia, this prevented the direct combat of NATO and the Western armies. In the tensions between India and Pakistan, the possibility that the parties will use nuclear weapons is a deterrent, and in North Korea America's direct attack was avoided as a deterrent, and the approval of this country's decisive nuclear response in the event of an assassination attempt on its leader is a guarantee and a strong deterrent for the enemy against any kind of mistake.
