Diplomacy operates under a crucial principle that emphasizes the importance of maintaining opportunities for dialogue and compromise. This concept is articulated in Barbara W. Tuchman's book "The Proud Tower: A Portrait of the World Before the War, 1890-1914," where she explores the intricate dynamics of international relations leading up to World War I. The idea is that by leaving room for negotiation, nations can navigate conflicts and avoid escalation into violence.

This approach to diplomacy underscores the value of flexibility and open-mindedness in discussions. Rather than adopting rigid stances, countries are encouraged to consider alternative solutions and foster a spirit of cooperation. Tuchman's analysis serves as a reminder of the delicate balance required in diplomatic engagements, where the potential for negotiation can ultimately lead to peaceful resolutions rather than confrontation.
