Ferguson (history, Harvard U.) argues that the US is an empire, although that's not necessarily a bad thing. Unfortunately, he contends, it is a bad thing that the US is largely not self-conscious of itself as an empire and is therefore unable to learn from the achievements and failures of past empires and is likely to remain non- self-conscious for the foreseeable future. For the new paperbound edition, Ferguson adds a preface defending the work against some of its critics and considering the implications of the invasions of Afghanistan and Iraq for his thesis.
