Answer:
On the side of Wilson, that is, for the adoption of the Treaty of Versailles and the ensuing entry into the League of Nations in order to continue direct intervention in European affairs, a significant part of both the ruling circles and the "public" spoke. Wilson's position was supported by prominent business leaders. The defense of the Treaty of Versailles focused on proving the United States’s worth of creating the League of Nations. With the help of the league and the Versailles Treaty, senators Hitchcock, Kellogg, Owen and others said that the United States will be able to rebuild Europe, sell its goods widely, which will improve the country's economic prospects for many years to come. The mandate system will open access to the colonies, to the Turkish Straits, to Middle East oil and other raw materials.
But the central argument of supporters of the Versailles system remained the argument that through the League of Nations the United States will be able to gain the position of the dominant power in the world. Senator Owen argued during the discussions that the League of Nations has a whole arsenal of means - diplomatic pressure, arbitration, and the International Court of Justice, boycott, blockade, the use of collective armed forces - and with their help the fate of any international dispute can be decided. Wilson’s supporters said the US’s joining the league will help “overcome social unrest in Europe,” stop the growth of socialist forces.
The opposition to the Wilsonists was called isolationist, although it itself did not recognize this name. The term "isolationism," despite all its conventions (in fact, it did not mean calling for the isolation of America), nevertheless had a constant content: the rejection of political and especially military alliances with Europe, 'bequeathed' by George Washington in 1796.
In the Senate, the first movement was a bloc of so-called “irreconcilable” (with a fluctuating number of 12 to 36 out of 96 senators), headed by William Bora, one of the most critical opposition leaders. Bora, Lafollett, Norris and other senators of this group 'attacked' the League of Nations as a tool for drawing the United States into alien wars, in defense of extraneous interests, and protested against anti-Soviet intervention.
