Query: cold war maybe dead, but its a hot topic!

so far, i have read the idiots guides to ww 1, ww 2 and i just finished the "idiots guide to cold war" and let me tell you, this is a great book. it is full of information that is either forgotten or rarely talked about. i learned a lot! the book starts off with the end of ww1 and continues into the mccarthy era. then, it goes into vietnam and finally ends up to sep.11 2001. pretty in depth. the only reason i gave it 4 stars is because the korean war was a little skimpy. but overall it was good just the same. it is recommended!
