I wanted to write something today, but had to shut down my comp. before I could finished it...
We touched that scenario when NATO would move into Ukraine and establish a security zone somewhere in the western corner of Ukraine. I believe another scenario exists, nearby, but involves a different country.
Hearing the news that Wagner moves to Belarus, Poland and Lithuania started to moan that Wagner relocated for the intend to cut off the corridor between the two country never mind that the corridor is between Kaliningrad and Belarus, where Lithuania did held off the traffic.. Gallant Germany calmed them and said they are ready to move a brigade there.

Note 1: Belarus technically still is a sovereign, independent country.
Note 2: since the start of the war NATO builds up forces in Central Europe and the Baltics.
So the other scenario: what if the cause and effect are the other way around, and relocating Wagner to Belarus - as well as moving nukes there as well - is a reaction to the NATO buildup?
What if NATO plans and invasion against Belarus? Or perhaps a riot which they would inflate into an "uprising", a "revolution" - a Maidan - which they would support with troops.
And even if this plan never bears fruit, it could serve as a distraction, could keep some amount of Russian forces occupied in Belarus, essentially doomed to idleness.

In the morning I read an article on Al Jazeera, where Stoltenberg acknowledged that Wagner is in Belarus, and said "not many". Well "not many" is a relative term. Less than half can described as "not many" to be honest. In same article Lukashenko was quoted talking about "camps" plural.
I can't find that article (don't really want to to be honest), but here's another one claiming noone from Wagner is in Belarus yet, still in their Anthill where they were. What is  this hide and seek?
