Second Cold War, Cold War II, or the New Cold War is a term that has been used by analysts and scholars to describe the growing geopolitical tensions between the United States and its allies on one side and China and/or Russia and those partnered with either on the other side in the 21st century.
This term draws comparisons to the original Cold War that lasted from the end of World War II in 1945 until the collapse of the Soviet Union in 1991. During the first Cold War, the world was divided into two opposing sides: the U.S. and its allies on one side, and the Soviet Union and its allies on the other.
This Second Cold War, however, has no definite meanings. Rather it has been variously referred to relations without agreement by various sources on the existence and development of this Cold War.
