> That means that once a peace deal is signed, Ukraine will need to be permanently armed to the teeth, much like South Korea. That would ensure they can defend themselves without NATO membership. If Putin doesn't like that outcome, well he shouldn't have invaded in the first place.

Russia demands heavy restrictions on the size of the Armed Forced of Ukraine, essentially turning it into a small, lightly armed, and easily defeatable infantry force, with a veto on any foreign military assistance to Ukraine if Russia were to attack them again. The goal of this is cartoonishly obvious, and makes a peace deal unrealistic, too.
