Really? OMG this is bad. The previous war between Ukraine and Russia isn't done yet and now this one between Taiwan and China came? I think the negative effects that the world is feeling right now is going to get worsen but if this was about making Russia to suffer more, then I think some will like it as they also hate Russia for what they have done in Ukraine but still, it would be better if they think about the consequences first before they do such actions like if this can cause another problem or not.
If yes then better if they don't continue what they are planning as I think the tension between Russia and Ukraine can still lessen or end soon.
The guns brand changes only This time it is Russian gun, before it was American. Why was the world silent when the same was/ is going on with Palestine, Iraq, Afghanistan. Oh! Because they are European and they only care for white skin. The damage American guns did to the above mention countries are far more than done in Ukraine.
Even if we discard the fact that the events you listed often had various reasons, some of which really required external intervention, then this cannot be a reason to support Russian terrorism against Ukraine, and will not justify the murder of already several tens of thousands of civilians in Ukraine from Russian weapons.
At the same time, I honestly say that I did not openly support some Western operations in other countries, and I think that in some cases it was possible either to find another solution, or not to invent fake reasons!
