Austria's status of neutrality contended with crises almost immediately after its founding along with the 1955 State Treaty. First, during the Soviet invasion of Hungary in October 1956, Austrian neutrality faced the threat of conflict when Soviet-Hungarian clashes spilled over into Austria. Then, in July 1958, Austrian neutrality contended with more benign, but nonetheless disturbing, provocations from the Cold War's Western superpower, the United States. As U.S. military planes transited Austria in broad daylight on their way to Lebanon, the cozy, covert Austro-American relationship became all too overt. Although many Austrians believed neutrality would end foreign (particularly Soviet) domination and would ensure an ultimate withdrawal from global upheavals, these events showed that neutrality by itself could not remove the strategic implications inherent in Austria's position in Cold War Central Europe. Indeed, partisan strategic calculations in both East and West had played a significant role in creating Austrian neutrality. As a result, preserving both Austria's neutrality and its links to the West required delicate maneuvering by a small, poorly defended country amid Cold War crosscurrents of Eastern threats and Western sympathies. Already in its early years, Austrian neutrality proved to be less of the holiday from history that many Austrians expected during the festive mood of May 1955.
