In 2008, Buchanan published a book entitled, ''Churchill, Hitler and the Unnecessary War: How Britain Lost Its Empire and the West Lost the World''<ref>https://www.amazon.com/Churchill-Hitler-Unnecessary-War-Britain/dp/0307405168/ref=sr_1_1</ref> in which he criticized [[British]] [[Prime Minister]] [[Neville Chamberlain]] for granting security guarantees to [[Poland]] and unnecessarily causing [[World War II]], costing the lives of more than 50 million people. He compared former President [[George W. Bush]]'s decision on [[NATO expansion]] to include seven additional [[Eastern European]] countries including the [[Baltic states]] of [[Estonia]], [[Latvia]] and [[Lithuania]] as equally unwise. He warned that NATO expansion into the former [[Soviet Union]] could lead the US into [[nuclear war]] with the [[Russian Federation]] despite the fact that the US has never had any vital interests in Eastern Europe. | In 2008, Buchanan published a book entitled, ''Churchill, Hitler and the Unnecessary War: How Britain Lost Its Empire and the West Lost the World''<ref>https://www.amazon.com/Churchill-Hitler-Unnecessary-War-Britain/dp/0307405168/ref=sr_1_1</ref> in which he criticized [[British]] [[Prime Minister]] [[Neville Chamberlain]] for granting security guarantees to [[Poland]] and unnecessarily causing [[World War II]], costing the lives of more than 50 million people.
