What were the consequences of the Manchuria crisis on the League of Nations?

Once Japan had been determined the aggressor the League should have tried to remove its forces from China under article 10, but the League had no army of its own to deploy against the Japanese. The only countries with the strength to remove Japan were the U.S.A and U.S.S.R and they weren’t even members of the League. Nothing was done to remove Japanese forces as Britain and France weren’t willing to risk their armies and navies on the other side of the world. As the League had failed to induce military action against Japan the second course that they had to punish it with were trade sanctions.  

The League had often punished nations that broke the Non-aggression agreements with trade sanctions this is were members of the league refuse to trade with the aggressive state.

But trade sanctions against Japan could not even be agreed on within the League even on the sale of weapons to Japan. Even if they had been agreed trade sanctions against Japan would have been pointless as its main trading partner the U.S.A was not a member of the League and its second most important trading partner China it had invaded. Also the British were more concerned with keeping trading relations open and maintaining its empire by continuing friendship with the Japanese Empire.

The Leagues inability to react to an aggressor invading another country so openly greatly harmed its reputation.

In 1933 Japan left the League of Nations insulted by its findings that Japan was to blame. This was a large event as a permanent member of the Leagues council had got away with balayten aggression and nothing was done to stop it and it left the league when it spoke out against it. This showed that the league was truly powerless against large powers and it could do nothing to stop aggression, this greatly influenced other militarist regimes in Germany (Hitler) and Italy (Mussolini) policy.

I believe that the Invasion of Manchuria by the Japanese was the nail in the coffin of the League of Nations, It had shown the league could do nothing to stop and could only use talk to deter it. Showing it meant nothing in global politics and that any major power acting against a weaker one had no threat of attack from the ideal of collective security. This no doubt gave Germany the confidence to start annexing territory in 1936 and eventually start a Second World War.
