Reality of the European Security After the Cold War

The issue of international security remained confined to its European framework when the European superpowers dominated global security affairs. But in the first decade of the twentieth century it had seemed that the security and stability of Europe after the Napoleonic wars began to crumble with start of the First World War, that expressed through its consequences a clear change European affairs which had represented by the military participation of a non-European superpower (United States of America) in tilting the fighting to the capitalist democracies in Europe.
Since the end of the Second World War, the United States has embarked on building a security system in which European security has been considered as part of American national security, but that had face with the emergence of another global power versus the United States that is the (Soviet Union), which is intellectually contradictory to the West and thus had produced a Cold War that has casted a shadow over Europe after World War II until 1989.
