Well, not necessarily. In fact, can even be statistically expected.
If Luka's real support at ~20%, & siloviks ~1 S.D. more pro-regime on average, then loyalties amongst them are basically 50/50. Though conformity keeps them from stepping out of line. BUT.
Ofc a regime collapse that solidifies in one region can lead to something - the Veyshnoria scenario. en.wikipedia.org/wiki/Veyshnoria But don't see that happening in Belarus.
