The guy who tried to take over Ukraine's government to make it a puppet state, then tried that again when he originally failed, then tried to create an uprising so he could take over Ukraine, then sent in troops to kick off an uprising when that failed, then invaded, then invaded again... doesn't want to conquer Ukraine and would be happy with only limiting their military to a police force.
He has his authorities and propaganda constantly promote destroying and conquering Ukraine:

He even has the ex-president of Russia making fantasy maps showing Russia controlling the vast majority of Ukraine:
He personally wrote a manifesto about how Ukrainians aren't a people, aren't a state, calls them "Little Russia", and are part of Russia. He also straight up says he wants to unite Ukraine with Russia:
When given a softball question from Tucker asking for peace, said that if USA stopped sending aid he would be done in a few weeks and then the war would be over. Yet he doesn't want to conquer Ukraine because it's too costly? Yet he's still attempting just that despite the costs and poor results. He just wants to keep their military weak and give himself veto power on them receiving aid if they're invaded again because... who knows? Having accomplished none of his war aims, very little of his goal of conquering Ukraine, and having ensured that Ukraine would not have much of a military, thereby drastically cutting the costs of his future invasion, he would be satisfied and not attack again.
Yeah that's hopium. There's near 0 chance that Putin follows through with that agreement, much like he betrayed the Budapest Memorandum, Russian-Ukrainian Friendship Treaty, Istanbul Summit, multiple treaties with Georgia, multiple Minsk agreements, Syrian treaties, Chechen treaties etc.
