As noted above, much of the contemporary political discourse pertaining to Israel is rooted primarily in events that took place after 1948. For events prior to 1948, however, there is a wealth of resources available, some of particular note that I'd like to highlight may be of some use to you. Michael J. Cohen's Palestine and the Great Powers, 1945-1948 deals with the events immediately prior to Israel's establishment as an independent state, while Tom Segev's One Palestine, Complete: Jews and Arabs Under the British Mandate stretches out to cover a broader period from 1917 to 1948, though it is based primarily in Israeli sources, I will note. The official recommendations for Israeli history books are more likely to hold the answers to your actual questions about views on Israel, particularly if you balance sources like Benny Morris and Rashid Khalidi as representatives for each perspective. Although I understand your desire for non-biased sources, complete absence of bias will be difficult to achieve in any comprehensive study of Israel, and a thorough understanding of both perspectives from their perspectives, keeping their respective biases in mind, is likely to offer you much better insight into the conflict and its roots.

While not strictly about pre-1948 Israel, I would highly recommend The Lemon Tree. I read it in both high school and college--it was a big part of my college course, "Survey of the History of the Middle East." It feels like a novel, but it is a well-researched book that lays out the conflict in a very neutral way, showing how the creation of Israel affected both the pre-Israel inhabitants of Palestine as well as the Israeli settlers.

Although, if you are wondering about why Israel is so disliked, you might want to look into more recent Israeli history and politics. Even the U.N. says that Israel's wall is illegal, and the Human Rights Watch states that Israel has continued to infringe upon the human rights of Palestinian citizens. Although discussing contemporary Israeli politics is not the place of this subreddit, I hope it is okay that I've linked to a couple contemporary news sites to help point you towards the answer to your question.
