I would. While pickling is a good way to preserve food, the food itself needs to stay submerged in the pickling solution if not refrigerated. Acids used in pickling solutions are extremely hostile environments for bacteria.
Big caveat: Pickling and fermentation processes can be very different. One process may work to keep food safe for years, but others may only last weeks or days once the food is exposed to air.
Refrigeration slows down bacterial growth enough for days or weeks of storage, but eventually, robust bacteria will take over if there is just a little bit of air circulation. Warmer conditions with occasional air circulation and some kind of food source just increases the risk of bacteria development exponentially.
Before refrigeration was a thing, picking or salt packing was king. It works well, but it's easy to screw up. Heck, I think authentic/traditional kimchi production never uses refrigeration and relies on the acids as well as CO2 and basic ethanol production to stay ~~sterile~~ safe.
These days, just throw everything in the fridge. It's easier and safer because you don't know exactly what preserving processes were used.
Well, a direct invasion of the US is a bad option and the world knows this.
The problem is with Russia is state controlled media. If Putin was eliminated, the world probably wouldn't know for at least a week and that would give their media enough time to tell the public who else they should like instead. It wouldn't surprise me if there is a pre-recorded video of Putin "stepping down" or "retiring".
If you have ever watched Russian state media, you will see they are probably worse than the Ministry of Truth. Their panel discussions are disgusting, actually. Four or five different people, with four or five different "views" that all converge on the same exact points: West evil, Putin god, Russia war machine invinsible, Russians have the best society on earth, everyone else is a nazi.
(I don't want to exclude the rest of the worlds media either. Most major outlets have their own agendas for sure, but Russians probably get the most blatant version. They don't even hide it.)
