The book is a period book. It had relevance during the Iraq war period and is probably not so relevant to today's context. However, looking back two decades and how the world moved and the USA withdrew from Afghanistan, there is a need to relook at the current USA probably does not carry that much hegemony as it did two decades back. China is the second superpower that can economically challenge the USA. Military superpower is a thing of the past. With the USA so dependent on China's imports may not have the univocal power in the international circuits.
The book explains in several details how the USA has been a party to much international unrest. The book highlights the US's interest in the resources of South America or the middle east. Sometimes, the USA has supported non-democratic dictators in such regions. Towards the end, the book mentions USA's interest in exploiting space for warfare using her star war programs. The USA's interest in world peace is of passing concern. The USA is only interested in her national interest. Many times, the USA has acted on specific regimes just on a doubt that they may pose a risk to them than actual risk.
