What would happen after Russia loses the Russo-Ukrainian war?

Thank you, God for helping me make this.
Russia loses Black Snake Island to Ukraine.
Russia is very close to losing Crimea. Russian artillery fire at Kherson, Sumy and Kyiv. 
350,000 Ukrainian soldiers and 400,000 Russian soldiers fight in Sumy.
The battle was long.
Russian troops are deserting and transport aircraft are bringing soldiers to Crimea. Putin orders soldiers to build a stronghold in Crimea.
After 20 months the construction is done. Ukrainian planes bomb and strike down the Russian planes.
Ukrainian soldiers defeated Russian soldiers. 
Ukraine lost 40,000 soldiers and Russia lost 350,00 soldiers. The rest surrendered or retreated. Belarus joined the war and charged toward Kyiv. Second Battle of Kyiv was a 2 week battle, ending in a Belarusian defeat.
Belarus lost 60% of soldiers on that battle wile Ukraine only lost 20% Belarus refuse to retreat. Belarus send airstrikes in Ukrainian soil. Russia retreats from the Eastern parts of Ukraine. Russia can't afford to lose Crimea. Ukraine drove Belarus out of it's northern regions. Russia send refinforcments, tanks, helicopters, and armed trucks.
Seize of Crimea was a 240 day seize between Ukraine and Russia it was the bloodiest battle in the war.
Russian arterillery start firing at 8am. Two Ukrainian soldiers were killed in the atatck. A Russian sniper sees a huge horde of Ukrainian soldiers, he gets his sniper rifle ready and shots three Ukrainian soldiers, unknown to him there was an Ukrainian sniper that was ready to fire at him. The sniper kileld the Russian sniper. The other sniper in the watch tower yelled, "They're coming!"
Russian and Ukrainians fire at each other. Ukrainian tanks charge at Crimea, a Russian helicopter fly in the air and was shot down by the tank.
The battle lasted long. Ukraine won the seize of Crimea, but the battle was costly and deadly.
Ukraine: 600,000
Russia: 1 Million
Causalities:
Ukraine: 500,000
Russia: 800,000
The rest survived or captured.
Ukrainian assaults threw smoke grenades so if they charge the Russian snipers won't shoot them nor the Russians won't see them.
Russia sent a missile to Kyiv and it caused major damages and even destroyed an American embassy in Ukraine. United States joins the war and they enter Russian soil. Russia has the home advantage. Russian troops desert or protest. Russian econmony and military crumble.
Russia sent a nuke but it blow up in midair. 
Russia lost Kursk. Estonian, Latvian and Lithuanian troops capture the Russian city of St. Petersberg. 
Russia surrenderes.
Russia lost chunks of their land to the baltics, Ukraine annexed the European part of Russia and even annex Moscow, US seize all Russian military equipment and improve them and Russian nukes were shared among the NATO countries. The Asian part of Russia were annexed by China. 
The countries that border Russia abolish mandatory military service because they have that because they are scared Russia will invade them but since Russia doesn't exist anymore they are safe. Ukraine finally joined NATO along with Georgia, Kosovo, and Finland.
