It was hoped that the U.S. would use conventional and nuclear weapons to strike at Soviet staging areas in the occupied Baltic states in case of a Soviet attack on Sweden. Over time and due to the official neutrality policy, fewer and fewer Swedish military officials were aware of the military cooperation with the west, making such cooperation in the event of war increasingly difficult. At the same time Swedish defensive planning was completely based on help from abroad in the event of war. Later research has shown that every publicly available war-game training, included the scenario that Sweden was under attack from the Soviets, would rely on NATO forces for defence. The fact that it was not permissible to mention this aloud eventually led to the Swedish armed forces becoming highly misbalanced. For example, a strong ability to defend against an amphibious invasion was maintained, while an ability to strike at inland staging areas was almost completely absent.
