During the Cold War, the United States fought many proxy wars against Soviet-supported Marxist-Leninist and socialist states, but after the Soviet Union's dissolution, the US found itself as the world's sole superpower and was even deemed by some political theorists to be the world's sole hyperpower.[2][3][4] Political theoreticians of the neorealist philosophy (known by many as neoconservatives) self-styled as the Blue Team, increasingly view China as a military threat,[5][6] but there are relatively-strong economic ties between the two powers. Blue Team members favor containment and confrontation with China and strong American support of Taiwan.[7]
