Peter Zeihan has a lot of interesting POVs. I'm half way through his first book 'The Accidental Superpower' and he makes convincing arguments all around so far.
I find he continues to make solid arguments though and including his most recent The End of the World Is Just the Beginning.
I have to try to get through Guns, Germs and Steel again. Excruciating detail is a good way to put it with that book.
