How do Senate Republicans attempt to address concerns over the Treaty of Versailles and the League of Nations without rejecting outright the entire peace treaty ending World War I?

The Senate Republicans rejected certain provisions of the Treaty of Versailles and the League of Nations.

Explanation:

When President Wilson proposed for the Treaty of Versailles and an international organization which he believed would govern international relations and interactions, it was rejected by the the allied forces as well by the Senate Republicans.The Republican Senate leader, Henry Cobot Lodge was very skeptical about Wilson's proposal for the treaty. The Senate Republicans were against certain provisions of the treaty which they believed would hamper U.S's interest in world politics and economy.Lodge, therefore, proposed for certain reservations or exemptions and amendments in the provisions in the treaty which would enhance U.S's interest in the world politics.Wilson's failure to address Lodge's proposals in the treaty led Senate Republicans to vote against the treaty and consequently U.S failed to join the League of Nations.
