What did the Palestinians do to deserve the Balfour Declaration?

It's a simple question. I have not found a single pro-Israel forum member's answer to the question. This isn't in the religion section but I would accept a discussion of religion in this post because people tend to use their religion to support Israel. I've added documentation and perspective to help people find clarity.
