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
Yes. The international organization like United Nations can bring peace to the two countries but Ukraine will never forget the damage done by Russia,
So, if Russia fight with another country, Ukraine will join forces with the country to fight against Russia.
I don't think Ukraine will EVER forgive Russia for this invasion. And I am not sure any of the western countries will either.
The credibility of Russia has been permanently damaged by Putin and his acolytes.
