strongest russian soldier

I need your advice and input on a developing situation that has unfolded - to catch you up to speed, Russia (on behalf of President Putin) has invaded Ukraine and been at war with them for a solid year now. In response, most of the Western world has imposed strict sanctions on Russia, limiting its ability to gain resources to fund this unprovoked military conflict. China has pledged NOT to provide aid to Russia despite being technical allies, however they are receiving missiles and artillery from Iran and North Korea. They have only seized 1/5th of the country of Ukraine so far, but repelled heavily thanks to Western military and medical aid.

What should be done in this situation? If the war should end, what steps can be taken to stop this war?
