Lenin banned industrial vodka production for the harm it was doing to the population. Stalin resumed it, because the hole it left in the urban economy crippled the budget.
Fixing that sort of alcoholism is hard. It's hard as an individual to shake it, but when it ensnares an entire demographic?
It takes several generations.
That's if your government cares about having healthy citizens, and you could at least say the likes of Lenin wanted to improve the country, they were ideologically driven authoritarians, they had a goal, and thought it was the right one. People like Stalin,  Putin and Xi Jinping can't even be said to have benevolent intentions. Power is their main concern, and those under them are just fuel for the state's fire.
It's great that whenever these fires happen you never know if it was just Ukrainian Partisans, Anti-Putin Russians, people trying to avoid conscription, or just drunken soldiers being idiots. >

I think it's just lack of basic safety standards (very common in Russia). Looks like they were cooking inside the tent and a spark set it on fire. >

A spark burning down a tent is one thing, but that one tent fire burning the whole camp? Thats some high level incompetence. >

Depends on the material of the tents, distance from each other, and wind. >

And whether that was a bucket of water or vodka >

Brave of you to assume a bucket of vodka would remain undrunk in a camp full of bored, conscripted Russians who want to forget that they've been drafted to fight a pointless war. >

20 litres per year on average. >

Only 20 liters?  They need  more training. >
