How long was the Treaty of Versailles intended to be in order?

Question

After WWI Germany was forced to abide by the Treaty of Versailles. In the treaty Article 160 says:

By a date which must not be later than March 31st 1920, the German Army must not comprise more than seven divisions of infantry and three divisions of cavalry. After that date the total number of effectives in the Army of the States constituting Germany must not exceed 100,000 men, including officers and establishments of depots. The Army shall be devoted exclusively to the maintenance of order within the territory and to the control of the frontiers.

How long did the allies intend to prevent Germany from rebuilding their military past this point? Did they intend this treaty to last indefinitely or did they just expect Germany to break the treaty in the far future?

Answer 1

WW1 was billed as "the war to end all wars". The mood at the end was that this would indeed be a watershed event after which wars will become a thing of the past and the world will enjoy a peaceful and equitable future.

The Treaty of Versailles was supposed to be the permanent foundation for this future.

Specifically,

• The German disarmament was supposed to be followed by general arm reduction treaties encompassing the Entente (see, e.g., Washington Naval Treaty; the efforts to limit land armies were generally unsuccessful, but chemical weapons were banned and war was "outlawed").
• Colonies were supposed to be granted independence as they become "ready" ("mandate" system was created so that mandate powers prepare mandate territories for self-rule).

This was, of course, wishful thinking, repeated by FDR's dream of "4 policemen" during WW2 and GHWBush's "New World Order" at the end of Cold War.
