One thing is putting a country’s nuclear deterrence forces on high alert another thing is use these weapons.
I'm not an expert on psychology or Russian politics so I can't say if Putin has decided to use 1-2 tactical nukes in Ukraine or if Putin has ordered his military to put the country’s nuclear deterrence forces on high alert as a negotiation weapon in the negotiation with Ukraine.
