Final answer:
The Wall Street Crash exacerbated the financial turmoil, leading to bank withdrawals and failure, which significantly restricted the economic capabilities of nations, rendering them less able to enforce the military sanctions of the League of Nations.
Step-by-step explanation:
The impact of the Wall Street Crash on the military sanctions of the League of Nations can be understood in terms of the economic turmoil it created, significantly undermining the ability of nations to enforce such sanctions. Following the Wall Street Crash, there was a great withdrawal of money from banks, not only in Europe but also in the United States. This financial panic and the ensuing bank failures restricted the availability of credit and caused a suspension of loans globally, thereby decreasing the financial capability of nations to support military sanctions.
The League of Nations, which had no military force of its own and relied on member states to enforce sanctions, found itself even less capable as nations struggled economically. The economic sanctions imposed by the League became difficult to enforce as nations prioritized stabilizing their own economies over international efforts.
