Nukes? He’s only pretending, but no one believes in his threats anymore. There have to be more than one order to launch nukes.
And I’m not sure if it’s possible at all to use the nuke complex to attack in the first place. It was designed to be used as a weapon of vengeance, in case nukes were launched and targeted the country, it would just annihilate everything. There is a system designed in the soviet era for that purpose that guarantees the nuclear response. But I really don’t believe it can be (physically) launched if there is no launch registered from other countries. It would be such a flaw in the system if it could be used for attack purposes.
