The book is about Zionism and Israel (it is pro-Israel) and speaks about Israeli politics. So any background in this would be great.
The book is based on previously edited articles that were published in newspapers so the work should not be too hard.
On the other hand, while I did edit these articles to make them relevant to a book format, I might have missed time references such as "last week, this and this happened" and if I did miss some, I would love it if you found them.
Other than that, just regular proofreading and editing for spelling, gramar, sentence structure, flow, etc...
