In view of what will probably be a year of negotiations - attempted at least - between the United Stated and Russia over the fate of Ukraine and Europe, it is worth remembering that the Americans political leadership is considered today by the Russians as not capable of making agreements.
The Russians have a long but useful word for the incapability of sticking to agreement : “недоговороспособность”, i.e. agreement-incapable. This trait may become a liability for the United States, in possible upcoming negotiation with Russia regarding Ukraine and Europe’s security architecture. It is well known that the Russians’ approach to international relations is “trust but verify” (доверяй, но проверяй). But how is that possible when a duplicitous and false Uncle Sam simply cannot be trusted?
