War have never been a solution to any problem, that's why I believe that the only way forward is for the two side to go back to the negotiation table an settle their differences
Russia wants Ukraine and the Ukrainian people do not want to be a part of Russia how can they settle their differences when both will never budge in negotiations. Russia has invested years under Putin to make this attack on Ukraine and the people of Ukraine was never going to want to be Russian. The only way this gets solved is Russia gets defeated, Ukraine gives up a portion of Ukraine that Russia agrees to accept or Russia wins the war and takes Ukraine. This war could go on for many years because there is no way any of these happen in the next 5 years.
