To make negotiations successful, each of the parties should offer something important to the other and less important to itself. Politics is always about bargaining, with a whole range of bargaining chips. You need to give up something if you need to get something else in return. This is the true nature of negotiations, unless a party suffers a military defeat. During the Moscow negotiations Russia and the US were equal parties. This equality was not decided by a currency exchange rate or GDP volume, but rather by the fact that both parties have control over something important to each other. SOMETHING they cannot get unless they negotiate.
