Being brighter than Trump is not very hard.
However, I don't see any long term planning from Putin.
In 2013 he wanted to make a trade deal with Ukraine which would move Ukraine away from EU. Yanukovich signed it and that triggered euromaidan.
@AfonsoAlves correct me if I got it wrong.
For some reason he decided to seize crimea and start a separatist movement in donbas. My guess is, this was a purely emotional response for being rejected.
However, over the years he grew unhappy that he can't control ukraine anymore and has no chance of installing a puppet. So again he started a 3 week military operation. He wanted a regime change and Ukrainian Lukashenko. As that failed he was hoping to prolong the war until Trump was elected, as his best hope.
I don't see long term planning, because it doesn't make sense to wait 8 years between crimea and full invasion.
