The theory of clash of civilizations is a controversial theory, which puts forward that there is a fundamental conflict between different civilizations and it is a new form of confrontation after the Cold War. Samuel Samuel huntington, the proponent of this theory, believes that the change of global political structure will lead to the conflict between civilizations becoming the main form of international conflict. He believes that civilization is the most basic cultural unit in human history, and differences in values, beliefs, history and culture between different civilizations will lead to conflicts.

However, this theory has also received a lot of criticism. Some people think that the conflict between civilizations is not inevitable, but can be solved through dialogue, exchange and cooperation. In addition, some people think that the differences between civilizations are not fundamental, but superficial and can be reconciled. Others believe that the theory of clash of civilizations will aggravate cultural conflicts and hatred, which is not conducive to world peace and development.

Generally speaking, the theory of clash of civilizations is a complex topic, which needs to be evaluated by comprehensively considering various viewpoints and evidence.
