Putins ultimate need is as strategic buffer from NATO-especially now that Ukraine has advanced NATO weapons
He wants "deNazification" -some of that is true, some just rhetoric
He would like a land corridor to Crimea as well,and has that
Ukraine want to to rebuild, but escalates the war.. i dont see anything close to a cease fire yet

Ukraine has a fundamental right to fight for their sovereign territory.
Your insistence that they submit and surrender large and important parts of their country is a reflection of the soft American background that constitutes your cultural and historical milieu. Americans as a nation hasn't really been tested since the civil war.
The people of the East Slavic republics are hardened by history and cultural traditions. They are going to be tenacious in defending their home and hearth. In my experience, Slavic women are generally even tougher than the MAGA fat asses who stormed the Capitol on Jan 6.
