Though Some Scholars Argue for a "Second American Hegemony," Sanderson

Though some scholars argue for a "second American hegemony," Sanderson and Alderson think that:

A) the United States has not yet lost its hegemonic status and never will
B) this is quite unlikely, because no hegemon has ever lost and regained a hegemonic position
C) this is a very real possibility
D) this will coincide with a rise in European hegemony, thereby forming the first ever "dual hegemony"
