a rising power, but not superpower.
Agreed. A superpower is generally the top power (usually only one, but the Cold War produced two) on earth and can basically do anything they want short of invading another nuclear power. Even then, they could pull out a win in the end. Usually a superpower is not conquered but instead is destroyed from the inside, and it falls apart from political chaos, division, and generally a few natural disasters thrown in there as well...
