西方和俄罗斯可能进行的交易可以是，包括北约在内的现存的后苏联欧洲秩序的原则和机制不变，并且这些原则和机制为俄罗斯所接受和施行，而俄罗斯在北约内部发挥的作用得到极大地增强，包括未来取得北约完全成员国地位的可能。
The possible trade-off could be that the existing principles and institutions of the post-Soviet European order, including NATO, remain unchanged and are accepted and implemented by Russia, which would get a significantly enhanced role within NATO, including the perspective of full membership.
