Before the war began, the Abwehr was fairly active and effective as it built a wide range of contacts; they developed links with the Ukrainians opposed to the Soviet regime, conducted meetings with Indian nationalists who were trying to free themselves from British imperialism, and established an information-sharing agreement with the Japanese.[28] There was even some significant penetration into the extent of the United States industrial capacity and economic potential,[29] and data was collected by the Abwehr concerning American military capacity and contingency planning.[30]
