What started as a WWII alliance between the democratic Western Powers and the communist Soviet Union quickly turned to rivalry following WWII. Rebuilding Europe created competition as an anxious West watched Soviet influence grow in Eastern Europe. The atmosphere of fear was heightened by the threat of nuclear weapons. In response to building tensions and anxieties, the United States, along with 11 countries, signed the North Atlantic Treaty. The treaty formed the legal basis of the North Atlantic Treaty Organization, or NATO, to provide collective security against the Soviet Union. 

After the Soviet Union’s collapse in 1991, NATO evolved to focus not only on collective security, but also on peace-keeping and democratization. NATO’s new mission also meant more countries could enter into the alliance. Today, NATO includes 32 countries, raising questions about its continued expansion.

In this lesson, students will analyze primary and secondary sources to participate in a Socratic Seminar on whether NATO should persist in its expansion or reconsider its strategy. Through close reading and analysis of primary and secondary sources, students will deepen their understanding of the complexities of NATO in the 21st century.
