Going back months as usual, I finished by GH reading while at my in-laws' house for Succos. They have plenty of interesting reading material there, but everything was a bit disorganized because of construction. One thing I came upon was Alan Dershowitz's The Case For Israel, which definitely seemed promising.
I found it to be a thoroughly enjoyable, gratifying and very informative read. I then took my new-found factually-based arguments and commented on a Salon article. That of course was a mistake, in which I wasted a week raising my blood pressure to argue with a rude bully, until I gave up as it was taking too much time. But, that incident notwithstanding, I am very glad to have read this book, just so I can answer all those anti-Israel news stories in my head with solid, cogent, pro-Israel arguments :)
