Answer:
One example throughout history that we have seen types of government or economic systems cause conflict between two countries is the Cold War.
Step-by-step explanation:
The Cold War was a war that lasted about 45 years. This war was between the Unites States and the Soviet Union. The Soviet Union (or Russia) was a communist country, which means that they wanted lots of control over the people living there, and the citizens had limited access to everything outside their country. The US was capitalism, meaning the citizens had freedoms. The Soviet Union wanted to spread Communism, however, the US did not. That is what started the war.
