I think that this is all an exaggeration or at least for now.
I can see tensions growing between different countries but some countries from the east have partnered up with some countries from the west. I do not know if that is good or bad as you know no matter what happens or no matter what conflict arises, they will be both helping each other.
Russia's war against Ukraine has indeed led to a regrouping and aggravation of the situation between various blocs of states. First of all, these are countries that supply weapons to Russia - Iran, North Korea and partly China, and on the other hand - more than 50 countries that support the defense of Ukraine from Russian aggression. The outcome of this war will determine what the format of global security in the world will be in the future.
Your comment is very reasonable and it gave me a new perspective about how the world will be in the next few years. The war in Ukraine has really divided the world into two blocks, and we might end up seeing the manifestation of these divisions in the future. Nations like South Africa that is known as pro-west have decided to support Russia.
But I want to add that the war between Israel and Hamas is gradually shaking international alliances. We are seeing countries like Spain, Ireland, and Norway recognizing Palestine's statehood regardless of the anti-statehood position of some Western world powers.
However, we can say with confidence that Russia will come out of this war weakened, and many nations and nationalities that are now being held within Russia by force will certainly take advantage of this, and we will soon, with a high degree of probability, be able to observe how Russia will disintegrate into many separate republics.
I am afraid I don't share the same thought that Russia will become weaker after this war. This war has made the Russian state advance its military technologically. The Russian state start the production of many sophisticated weapons through the assistance of their allies. Economically the country is not also doing badly. So I don't know where the weakness will come except Putin is removed as president.
