Of course, the USSR fell a year later so you’ll likely argue the deal was null and void. But if a verbal agreement by the US to the leader of the USSR could be broken so easily a few years later, it’s no wonder the promises that America makes to other countries are viewed with such suspicion. And if America is free to ignore agreements, then so is Russia.
I’m not rooting for either side in this war, but I don’t fall for the ridiculous propaganda the western media is putting out. Both sides have legitimate grievances, but both sides should negotiate for peace today so this death and destruction can stop.
If you have a treaty to show between NATO and the Soviet Union, then show it.
