Fun fact: fiestaware plates (this was the company that made the uraranium glazed ceramics) are commonly used by radiation safety folks as check sources and for teaching how to use survey meters. This is because they usually aren’t considered a radioisotope source, so there’s less paperwork to keep them around.
Russia desperately doesn’t want Ukraine to join NATO or further their ties to the west. Agreeing to those terms plays direct into Russia’s hands.
There is a wide gap between “Russia stops their invasion and pulls their forces out of Ukraine” and “unconditional surrender by Russia.” No one is calling for the latter, the former is a very reasonable outcome.
