The Rise and Fall of Great Powers
USA ใกล้ล้ม? จากเจ้าหนี้ → ลูกหนี้ และ 5 สัญญาณขาลง
Summary
In 1945 the United States was the centre of the world economy. The question is whether it is now in decline.
The frame is Paul Kennedy’s imperial overstretch, whose iron rule is that economic capacity underwrites military power.
The five signals: strategic commitments, ever more expensive weapons, the contest between guns, butter and investment, falling relative power, and internal division.
Key points
Relative power is what gets measured
A great power does not need to get worse to lose its position. Others only need to improve faster.
The usual response accelerates the crisis
Raising military spending to hold the position erodes the economy that pays for it.
Postwar Britain is the closest comparison
An empire still large and no longer affordable is a shape that has already occurred.
The frame predates the current situation
Kennedy wrote in 1987, so this is not a retrofit to today’s headlines.
