Sounds more like an attempt to intimidate the Iranians by leaking something like this to Tucker to send a message.
Nothing Tucker said is new. The idea that nukes were floated as an idea was news months ago which is why Trump publicly said he wouldn't use nuclear weapons. The idea that Netanyahu is pressuring Trump on this war has been cycling around ever since Trump pulled out Bibi's chair for him to sit down in at the White house. Tucker just put them both together and said the decision with imminent. Nothing new and something everyone with a clue about jews was already speculating.
IMO, no nuke will be dropped because Russia said a long time ago that if the USA nukes Iran, then they will nuke Ukraine. This isn't an idle threat either.
But, the USA is still pretending to float the idea in hopes of getting a better bargaining position with Iran.
