We all already know some of the reasons why Russia and Ukraine have conflicts as reported in many media today
and this tends to be the attitude of Russia's Separatism
and this war will not easily stop or there will be peace
Can the international world as the United Nations (UN) bridge these two countries so that they can make peace or to stop the Russian attack on Ukraine
The war is not just between Ukraine and Russia. Its war between Europe and Russia and the frontline is Ukraine, where Russian bombs are killing innocent Ukrainian children. As for the issue of international relations, The most powerful thing is political and economical isolation, which of course is very bad for everyone but may help to stop war.
Ukraine was simply the excuse, Putin doesn't want NATO next to his country, which was also a country that belonged in the Soviet Union, a large part of their territory is Russian and their citizens are Russian - speaking for the very same reason.
The war isn't going to stop anytime soon, unless Zelensky surrenders and meet Russia's demands, something which is currently highly unlikely. Putin will keep going till he gets what he wants, one way or another.
