Probably not. But the question has to be addressed in a wider context, recognizing that in the aftermath of the war a great many Americans concluded that US participation had been a mistake and that in the future the country should refrain from intervening in foreign quarrels. America's rejection of League membership was an aspect of this widespread embrace of isolationism.It should also be noted that the League's principal foe in the Senate, Henry Cabot Lodge, was not an outright rejectionist. He objected mainly to a clause in its charter that would have empowered the League to call on US military forces without the approval of Congress. If that clause were revised, he was willing to support US League membership. But President Wilson refused to compromise on this issue and this killed any chance that the Senate would approve League membership.Thus even if the US had joined the League, it would have been with many qualifications.
