If the country is doing fine under his goverment, then no problem.
I suppose hypothetically that is true, but the problem is that it would be hard to agree on a definition of "fine".
"Fine" could mean that people are doing well economically and not being rounded up and shot for some range of normal activity. It could mean "better than Ukraine".
On the other hand, this was really why I posed the initial question about what the succession plan is, because I think you will find that this can be an awkward moment in the development of dictatorships. So things may be "fine" to some degree now, depending on your perspective - it is certainly not my perspective - but there is clearly a problem being stored up. Also, thieving, corruption, and unchecked power will eventually destroy any state, because there are no limits to its growth.
