What do you think would happen if Putin was assassinated right now?

He will be putin a coffin

They will be russian to put him in the ground.
- Lenin on the shovel after stalin long enough to only dig half the hole.

He would die.

Technically correct. The best kind of correct
What if he have nano machine, son?

During his next public speech, you'd notice that his eyebrows are slightly bushier, his voice is slightly deeper, and he's suddenly an inch taller.

No matter who actually did it. Russia would blame Ukraine/NATO/USA/The West in general, together and separately in rotation.

After that I have no real idea, who would succeed. There would be a massive power struggle both in the government and military.

There is a strong possibility that several of the autonomous regions within the Russian federation would try to break away. There is about a 20% chance of a civil war because of this.

And about a 1% chance of nukes being used.

Well Ukraine is on the table as a non-NATO source and obvious contender given the war.
- Ukraine would do it with the help of several other Western nations. A definite team effort!

There would be a power vacuum, probably a few murders/suicides/defenstrations, and the elections scheduled for a few months from now will probably be postponed during the struggle for leadership of the country. My guess is the powers that eventually take over will agree to pull out of Ukraine, conduct a few show trials, and do whatever else they think they have to in order for the west to lift the sanctions and unlock the oligarch's accounts.

It would please me greatly to know that Ukraine will outlive Putin.

Being a member of the KGB, he'd probably be replaced quick with someone who is just like him.

Didn't know they already build the Cloning Vat.
- Plastic surgery on a double for public appearances. Deepfakes for videos.
- If they had instead focused on Kirov production the Ukraine war would have gone very differently.

He would be dead

Nuh-uh, he'd be zombie Putin.
- Evil undead Putin... Wait if you are a terrible person alive. Do you become a good undead? Is undeadness a guaranteed aliment switch?

He likely has a dead man's switch to release the trump hooker piss tapes

I would feel better albeit for just a moment.

Putin might never be allowed to die... (even if he already has).

I can't imagine Russian fakery would be that good. This could be out of a comedy sketch.
- 40k?
That'd probably be true for a while, but after that they'd need to start an "election" where some military commander or other higher up will take his chair.
- Fascists do not care about truth or facts, only authority, so whichever they deem more useful to them at the time they will make use of.
Something like Futurama's heads in a bowl?
- Life imitates art. He died, they put his head in a jar and then just kept going.

An even worse Putin coming to power.

destabilization until the Kremlin finds a new president in that time probably multiple nations would be indipendent and Ukraine would pretty much launch their offensive and the union state collapses and tv stations all across Russia hijacked

Nothing.

There would be another president & the west wouldn't be happy with that one either

A hardliner will take power (Putin is not the most antiwest russian politician) and then...from the total erasing of Ukraine to third world war, anything would be posible, but neither civil war nor colapse of Rusia. That is the OTAN countries wet dream.

Putin is the most antiwest Russian politician. And the least antiwest Russian politician. Also the tallest one, as well as the shortest.
- Like a Putin for each one taste.
- Is there anything that dude can't be?
This is very likely. If anything, the existing system will be perpetuated because there's no replacement atm. It's been too long in the making and it will take a lot of work to undo. Also, he may be long dead and it won't change anything in the near future.
This said there's always a chance for a change, but not right now.
- What about a change in the West? In order to avoid another Afganistán, Irak, Sirya, Libya and so on...

By most accounts, the next man up will be worse, and that's really saying something.

Worldwide party for the last 10 minutes as every nuhe Russia has gets launched

Probably.
