As I consider a future political and economic agreement with Great Russia to be the immutable aim of our foreign policy, we must attempt at least not to make an enemy of Russia... I refuse to support Poland, even if that means that Poland will be eaten up. On the contrary, I reckon with this, and if at the moment we cannot help Russia to regain her old Imperial frontiers, we should at least not hinder her from doing so... The same applies to Lithuania and Latvia.
