No, "we" did not, it is russian propaganda. And if we are talking about broken promises, there was this thing called Budapest Memorandum.

And the Minsk agreement, the charter of the UN, and a bunch of treaties signed within the Council of Europe that are supposed to safeguard self-determination and deter agression.

When the other party is painted as the enemy, tearing down treaties is seen as an act of national pride. See Germany with the Versailles “Diktat” and Trump with the Iran nuclear deal and Paris agreement.

This promise is disputed. We only have the word of a few (mostly Russian) officials about it, unfortunately explicit on the issue was set on paper.

Promise is not disputed. There are no signed papers - there is no promise.

Whenever it was discussed at all is 1% a purely academic dispute and 99% demagogy.

Yes, it's based on a misinterpretation.
