You have all the powers that Putin currently does. Everyone feels the same way they do about you that they used to about Putin. You have his authority, for as long as you can hang on to it. You have none of his knowledge, however. The economic, military, social and political situations are the same as they now are. You are not inhabiting Putin’s body, you are just you. You’re magically transferred to the Kremlin.
How do you avoid falling out a window onto a pile of bullets your first week?
Do I have access to his personal bank accounts?
Someone asked a very similar question yeasterday.
Yeah, this is a riff off how of all the answers in that thread, none of them seemed to worry in the least about personal survival. All the answers about reforming Russia when they probably would have been couped in a day.
And yes, you presumably would have access to his bankers.
Realistically, nobody who has managed to reach Putin’s level is going to walk away. You’ve been plotting 24/7/365 since forever; quitting is not an option.
In the scenario you post the only thing one can do is to make a one time deposit of $100 million to a Swiss bank account, and then ask the security detail to escort one to the US embassy [the idea is that I am myself, just somehow in Putin’s office].
Once at the Embassy I claim to have no idea how I ended up in the Kremlin.
