This isn't going to be the last time our relations with a major friendly power are strained. We strive for good relations with all countries, but from time to time issues are going to arise and big powers have their own interests and will exercise their influence to get their way. We may be old friends, but when our interests diverge, or even when our approaches to the same problem differ, they have to put their interests first and their approaches first and so must we. This is a reality of the compelling pressures of international politics and of national interests and we must remember this.
