Un tethered from reality is hardly new. Ronald Reagan had his astrologer: https://www.pbs.org/newshour/politics/reagan-familys-trusted... ; American politics has little to do with the "reality based community".
Nor is "US carries out murder campaign in Latin American country for unclear reasons"
There ware some claims that Putin consulted shamans over the use of nuclear weapons, wanted to get their blessing.
It seems it was her wife who pushed for that. By reading the article, it doesn't sound like he believed any of that.

So we can't really tell to what extent, if any, those consultations affected the actual policies.
In general, I don't trust politicians by default. Still, I also don't trust astrologers (and even less so), so there is no reason for me to believe the astrologer more than the president.
