That could definitely be argued! The WWI was fought in Europe, so many European countries were left in pieces at its end. So they were definitely in need of outside support. One may also look at it from another point of view. The US refused to join the League of Nations, which shows that the country was not necessarily as involved in world affairs as it could have been.
Alfred Thayer Mahan recommended that the American military should focus on sea-power as the key to its success in any contemporary or future conflicts.
