I saw this posted by a couple people on my Facebook feed. In truth, I don't really know what happened in the events leading up to the Nakba and could use a good faith interpretation of them. I'm sure this image has plenty of falsehoods, but it would be helpful to know exactly what they are and how they can be debunked.
The Palestinians do not govern themselves, Israel controls virtually everything in the Palestinian territories; even the nominal Palestinian officials need Israeli permission just to move between parts of their alleged territory. Pretty much all the Palestinian "Authority" does is issue press releases.
