Power vs. Prosperity

John argues that when faced with security concerns, nations may sacrifice economic prosperity for survival, as seen in the lead-up to World War I. He distinguishes between structural realists, who view competition as driven by the system's anarchy, and human nature realists, who attribute it to inherent desires for power. Additionally, he explains the divide within structural realism between defensive and offensive approaches, asserting that states often seek opportunities to increase their power whenever possible.
