Anglo-American+Guarantee

The Anglo-American Guarantee on June 29,1919, was a Treaty that proposed to France that in case of a repeat of the German Invasion, both the United States and United Kingdom will come to France's aid.

This was significant at that time since France was extremely concerned with the possibility of a future attack, so it desired to dismember Germany in a way that it would be unable to mount a future attack again. The plan included a removal of Rhineland from the state of Germany and a creation of a new state (controlled by France) in its place, not only to weaken Germany, but also create a buffer zone between the two nations. However, unfortunately for France, the Treaty was not ratified by the U.S Senate so therefore, both signatories of the Guarantee withdrew their promises. Most importantly, the failure of the Anglo-American Guarantee on peacekeeping is that it caused the French leaders to feel betrayed by their allies, Invasion of the Ruhr 1923, no British commitment to France until 1939, and the Locarno Treaty in 1925.
