Final answer:
The provided information does not directly reference Geiss's thoughts on the Treaty of Berlin. Instead, it discusses the Treaty of Versailles and its ramifications, including the military restrictions on Germany and territorial changes after World War I, which influenced the rise of Hitler and contributed to the events leading up to World War II.
Step-by-step explanation:
If we're looking for insights from Geiss on the Treaty of Berlin, it's crucial to clarify as the provided text does not directly discuss Geiss's thoughts on the Treaty of Berlin. However, we can discuss the context and consequences of other treaties such as the Treaty of Versailles and its implications, as highlighted in the information given.
The Treaty of Versailles led to seismic shifts in European geopolitics. It significantly disarmed Germany and imposed reparations and territorial losses on the nation. The Treaty was seen by many in Germany as unfair and humiliating, fueling dissent and the eventual rise of Hitler who capitalized on this discontent. Hitler's subsequent violations of the Treaty's provisions, especially through military expansion and remilitarization, were met with an international policy of appeasement due to the various powers' recognition of some unjust aspects of the Treaty as well as fears of another war.
President Woodrow Wilson's Fourteen Points outlined a different vision for post-war peace that was largely unadopted. The redrawing of Europe's borders created new states but also new tensions, as not all ethnic and territorial disputes were resolved. The Treaty of Versailles left a legacy of resentment and unresolved issues that would eventually contribute to the outbreak of World War II.
