One of Sikorski's political goals was the creation of a Central and Eastern European federation, starting with the Polish-Czechoslovakian confederation. He saw such an organization as necessary if smaller states were to stand up to traditional German and Russian imperialism. That concept, although ultimately futile, gained some traction around that time, as Sikorski and Edvard Beneš from the Czechoslovak government-in-exile, signed an agreement declaring the intent to pursue closer cooperation on 10 November that year. On 24 December 1940 Sikorski was promoted to generał broni. In March 1941 he visited the United States; he would visit USA again in March and December 1942.
