¿Details about the war so far with Ukraine and Russia lead to a possible WW3?

As Russia continues to unleash upon Ukraine,  countless number of people have lost not only their homes but also their lives. Some have fled to neighbouring countries such as Europe while others remain in Ukraine and are being affected in the global state. 

Some are in desperate need of medical attention. It is estimated that roughly around 11 million people are finding it difficult to have sustainable food, ⅓ of the population is unemployed, and now they have to sleep in the harsh cold without any power. 

The gradual degrading of Ukraine economic activities has also impacted other countries such as Indonesia. Ukraine was exporting grains, and since the war began, their storage have degraded now, causing other countries' government leaders to locate new sources, which is opposing to be a problem. 

Even though this war is not ideal some countries are seemingly supporting it such as China, Belarus, Iran, Turkey, North Korea, Myanmar, and India who are helping Russia with the attack while on the other hand Ukraine too has received assistance from the United States and the European Union.  

Although it is understandable why countries are willing to help Russia since Putin sent out a threat to anyone who is going to help Ukraine, it also helps with their countries development. 

However, that is still not a very valid reason to engage in warfare, especially one without a very logical reason behind it. If Putin wanted Ukraine's territory, then after the war, there won't be any land there for him to inherit since he is destroying it all. Innocent people are suffering because of one man's greed and hunger for power. 

Since Putin is already engaging in what Russia was always famous for [WAR] and trying to conquer Ukraine, he is retaking the very footsteps almost every past leader of Russia has such as Vladimir Lenin and Joseph Stalin. And already with Russia's cold blooded history and the looks of the war between not just Russia and Ukraine but also Iran and Israel the chances of World War 3 [WW3] happening are more than likely high.
