On the other hand it seems that the economy of Kazakhstan was one of the best among other stans. It is possible that prolonged covid restrictions also played the role.
(this is what every russian bot is saying)
TL;DR: do not bring a flashlight or guitar to a gun fight. Drinks (cocktails in particular) on the other hand...
In Almaty, the protests got violent with killings and mass looting. A few other cities saw looting and destruction of ex-president's statues, but most of Kazakhstan was peaceful, including the place where the original gas-price protests started. The violence part does not represent the sentiment of the majority, I would bet, it's something organized; I don't know by whom and for what reason.
Which source? The one that requested Russian intervention? Why there are lots of videos of protests, shootings, killings by the Kazakh army, and looting by unidentified people but only words of the interested party for this one?
I don't remember the "AC unit" but I do remember Russian media's "100% sure version of 2 Ukraine planes downing the Netherlands' jet" a few years ago (with interviews of "experts" all over the place). That was their position for a long time (maybe half a year, until they shamelessly changed it to "Ukraine BUKs did it"). The "beheading story" seems like a fairy tale from the same authors.
BTW, it has nothing to do with Kazakhstan's legitimate goverment, which is free to request military assistance from an organization (not just from Russia, if it matters).
