Question

Why did the Republican Isolationists refuse to ratify President Wilson’s League of Nations? They were angry about the president’s decision to take only one Republican to the peace conference at Versailles. They thought the League favored European colonization that would hamper the United States’ powers. They thought the League tied the United States to Europe and their conflicts going against traditional US policies about international affairs. They were opposed to Article 10 that could infringe upon the United States’ right to declare war and expand its territories. NextReset

Answer 1

I believe the last option is the correct one - They were opposed to Article 10 that could infringe upon the United States’ right to declare war and expand its territories.
This particular Article meant that anyone could call America for assistance in times of war. Obviously, the US politicians were against such a decision, even though France and Britain wanted to sign it. In the end, nothing happened with this document.
