Yes military activity is reduced, what does this mean? It's a vague term like special military operation , in the west the term is plausible deniability
Which means it can be everything, and nothing
It's a legitimization , of the Russian demands, and Kiev agrees to some terms, which is already a good progress
Troops numbers will not be reduced, but activities will, which is a way of saying, what has been occurring for the last 2 weeks will continue
The fighting will move to Donetsk, and the grouping in Slavyansk and kramatorsk will be pushed out, where they go next is up to Ukraine
After donetsk is finished I imagine there will be a new set of demands on Ukraine, and from here the conflict can be controlled
Let's not fight here, but let us fight here
Yes it is a cynical approach of the Kremlin but an excellent one to reduce its operations throughout the front
We saw this in Syria
My guess, is donetsk will fall quickly
If the Ukrainians break the agreement to remain quiet near Kiev and Chernigov then after Donetsk, it will resume
Either way it is a de facto political agreement to localize the fighting , which a winning party can enforce, in this case Russia
If Ukraine had the initiative they would wholly reject the demands and retake their territories
So it is a de facto imposition of terms , stop fighting where you have lost we will "cease activities" but we will liberate Donetsk.
After that "phase 1" we will see how it goes
It is called "normalization " the enemy is psychologically processing what occurred just now
They have essentially agreed to destroy the VSU in donetsk , idk what kind of agreement that is, but let Kiev figure it out
