International terrorism is the result of a liberal world order.
All throughout the post-war period, the Soviet Union kept the world from complete disaster and complete wildness.
This case represents a manipulation of historical facts to downplay and justify Russian aggression towards European countries. See similar cases here.
It is important to mention the The Marshall Plan, also known as the European Recovery Program, which was a U.S. program providing aid to Western Europe following the devastation of World War II. As the designer of the plan, George C. Marshall himself said: "Our policy is not directed against any country, but against hunger, poverty, desperation and chaos."
Central and Eastern Europe however fell under the Soviet sphere of influence and eventually behind an ‘iron-curtain’. As a result, at least 140 people lost their lives at the Berlin Wall in the Soviet Sector of East Berlin between 1961 and 1989. This lead to increased tensions between the United States and the Soviet Union, including a 16 hour standoff involving US and Soviet tanks at Checkpoint Charlie in 1961.
The powers of Western Europe formed the European Coal and Steel Community, which later evolved into the European Economic Community and ultimately into the current European Union. This effort primarily began as an attempt to avoid another war between Germany and France by economic cooperation and integration, and a common market for important natural resources.
