Take a look at anything written by John Lewis Gaddis especially “The Cold War: A New History” for lighter reading (if you’re only 300 words short). For deeper and heavier Gaddis’ “We Now Know: Rethinking Cold War History” is great. For a military intro, try “The Cold War: A Military History” edited by Robert Cowley.” All should be fairly widely available.
Good luck
I left the stuff I wrote about Pope John Paul II in, Im not Catholic, but I think he doesnt get as much credit as he should for the fall of Soviet communism. He was a very brave and committed leader and stood toe to toe with Brezhnev and never wavered. I loved the signs that were all over Poland that had the Soviet slogan, The Party is for the People and the Polish vandals added, but the people are for the Pope.
Sad that so many in America take our freedom for granted. They have no concept of what it would be like to lose just a part of our freedoms and yet they look at our President who is trying to bring some of that freedom to millions around the world as evil and call him a Nazi.
