Yes, assassinated, because things happen and no, I do not intend to assassinate anyone just because I use this word. And because things happen, there are contingency plans written for such scenarios, in every country. Do you think that national security services shy away from this because God forbid they talk about it?
I could speculate further that there’s always a possibility of unplanned action or power imbalance, or infighting etc etc that may further complicate things, but the bottom line is things of all kinds happen and they will continue to happen regardless of whether I talk about them or not.
