Alliance Systems
The Cold War caused nations to choose between the US and the Soviet Union
1949- NATO (North Atlantic Treaty Organization)- founded by the US
- reason: to respond to a Russian invasion of Western Europe
- US, Great Britain, France, Canada, and 11 other small countries joined
- idea: if one of them gets attacked, the attacker fights them all
1955- the Warsaw Pact
- Soviet Union made its own copy of NATO
- Soviet Union, communist nations of Eastern Europe, and a few others
- idea: respond to a possible attack by NATO
