Theur citizens couldn't actually stop the war and ordinary people can't do anything about it and they just have to deal with the current situation for them to survive. If being jailed would be their punishment, I'm sure that silence would be their last resort. If I were from another country, I wouldn't boycott all Russian platforms because they're already suffering a lot of sanctions.
Yes you are right that mate ordinary people can not do anything to stop this war and even some country can not stop them. But all we need to do now is to pray that their mind became a peaceful mindset so that they will stop and back to normal cause some country are suffering right now because of the deleyed supplies from them .
Many suffer from this war and this one needs to end. And to start the peace negotiation I think those sanctions will be taken out first since this is really the main problem on why the inflation rise up because there are limited countries who can buy oil in Russia, if they open back dealing oil of Russia for sure these we experience huge inflation will be lessen and we might get back to normal.
