They had all major democracies except the United States. Also, they included the three countries that posed the greatest threat to peace - Germany, Japan, and Italy.Too much talk and no action. That's why America did not join it.
The Senate was not happy with the idea of the League of Nations. They felt it a threat to their checks and balances on the president.
The simple fact is they were scared and did not want a second world war. After the first world war,Germany's resources were very depleted and had to build from scratch. Thus Germany did grow strong and powerful. Don't forget that Germany had more than one enemy. They were at war with America, Great Britain, Russia and many more. This was one country that is one tenth the size of America and they still held out for 6 years. So that gives you an idea of why the league of nations did not do anything at the start. Germany took over France in a matter of weeks, and I believe that even if the league of nations could have done something it would have been to late anyway. The war was inevitable. The league of nations took a lot of land from Germany and they wanted it back and one way or another, they would have gotten it. Hope I helped.
The League of Nations response to the Japanese expansion of 1933 was initially to help China as they declared Japan the aggressor in the situation. Ultimately Japan ended up leaving the League and keeping their troops where they were.
Britain did not disarm in the League of Nations due to a combination of national security concerns and the desire to maintain its imperial power. The rise of aggressive powers in Europe and the threat of potential conflicts made disarmament seem risky. Additionally, Britain sought to retain its military capabilities to protect its interests and influence globally, leading to a reluctance to fully commit to disarmament initiatives within the League. Consequently, the lack of trust in other nations' commitments to disarmament further justified Britain's decision to maintain its military strength.
The United Nations has passed resolutions regarding the threat of global warming. The seriousness of the issue depends on the individual nations. The industrialized nations mostly recognize the issue as a threat and, more or less, are addressing it. The poorer third world nations mostly feel that the problem wasn't caused by them and taking measures similar to what the major nations are doing will hamper their development of industry.
The failure of the League did not cause World War II, but it certainly was one of the factors. There were high hopes for the League of Nations, but unfortunately, it proved to be a very weak body, unable to agree on major issues, and bogged down in bickering, as stronger nations like England and France competed for political influence. In the 1930s, when a united stand against the rise of Naziism and Fascism was needed, the League failed miserably. For example, when Italy (under Mussolini) invaded Abyssinia (today Ethiopia), the Abyssinians begged the League of Nations for help, but the response was half-hearted at best. Sanctions against Italy were agreed upon, but not enforced; in fact, several member countries totally ignored them. The League was not able to get every member nation on the same page, nor was it able to defend a weaker nation against a stronger one. Eventually, Mussolini decided the League would be no threat to his expansionist goals, and he soon cast his lot with another expansionist, Adolph Hitler of Germany.
NATO
that is because terrorism causes threat to different countries.
To reduce the threat of attacks
Communism is the opposite of the American style free market economy The Communist countries were aggressively promoting there political system and the US correctly interpreted this as a threat to the US and it political influence.
Some countries in danger of disappearing due to global warming include Tuvalu, the Maldives, and parts of the Marshall Islands. Rising sea levels are a particularly significant threat to these low-lying island nations.
