You said "right now". If you want to change to "will be able to do in the near future, before the end of his second term", that's a (slightly?) different list. But it's also a different comment.
You said "anything", in the context of dictatorship. I only used items in this list which IMO you can reasonably say Putin, an actual dictator, can do. Right now. Except the first one! Because that was a joke, a reference to something he himself said he could do.
If you want to change to "anything which has backroom deal importance, not just bread and games for the masses, but the real things, if you know you know", that's a (slightly) different list.
He has functionally neutered Congress. It is almost completely meaningless and it is operating without an independent Speaker.
I think he could succeed in principle re: Mount Rushmore, to be honest. I think eventually people will cave in and agree to do it, and then they will just pray to cholesterol that they can wait it out.
Stand in the middle of fifth Avenue and shoot someone :)
Have political enemies executed
Get his face on Mount Rushmore
Disband congress
Disband the Supreme Court
Keep Jimmy Kimmel off air
Get Jon Stuart to shut up
Get James comey indicted
Get a national holiday named after him
Etc.
Even when we focus on things he tried to do, there is a lot he couldn’t. Let alone when you look at things he didn’t try to do.
