Question: The U.S express supported which federation?
Context: The Polish-Czechoslovak federation, or federation, was a political concept from the time of World War II, supported by the Polish government-in-exile and, to a lesser extent, the United Kingdom and the United States.  It was a revitalisation of the Międzymorze concept, proposing the creation of a federation based on Poland and Czechoslovakia.  The project had less support in the Czechoslovak government-in-exile, which believed it did not need Polish support against the Soviet Union, and was eventually sunk by the growing Soviet dominance, as Joseph Stalin did not want a strong and independent federation in Europe that could threaten his designs for Eastern Europe.

In 1910, it created a Committee on Social Reform chaired by Father Peter Dietz.  The committee supported the organization of labor; however, it became a strong opponent of socialist influence in the unions.

The French football champions are the winners of the highest league of football in France, Ligue 1.  Since the National Council of the French Football Federation voted in support of professionalism in French football in 1930, the professional football championship of France has been contested through Ligue 1, formerly known as Division 1 from 1933–2002.  Prior to this, the first division championship of French football was contested through a league ran by the Union des Sociétés Françaises de Sports Athlétiques (USFSA), an organization that supported amateur sport.  The USFSA's league ran from 1894–1919 and awarded 22 league titles before being suspended in 1915 due to World War I and the creation and success of the Coupe de France, which had quickly become the country's national competition.  The USFSA returned in 1919 changing the league into numerous regional amateur leagues that awarded no league title.  This system lasted from 1919–1926.  In 1926, the first division's reigns were handed over to the French Football Federation.  The federation organized and ran a league composed of the regional amateur league champions called the Championnat de France amateur from 1927–1929 and awarded three titles before the league was converted to the professional league that exists today in 1932.
