” made security guarantees to Ukraine, promising to protect it in case of Russian invasion, and we have chosen to ignore those obligations”
When the government fell to a coup, all deals with the old government were over. We never made any deal with the coup leaders.

You only get to control what you can grab by force, and everyone else has the same right to grab by force that the coup leaders used.
