OK, I'm done. This is a summary of the main elements of RexBrynen's edits and what I did with them: 
 # Statement regarding declared UNRWA plans to include the Holocaust in its curriculum: I restored it, but moved it to the "aftermath" section, because the plans were stated in October 2009, after the period this article focuses on. 
 # Statement that The Holocaust was not taught in West Bank and Gaza schools when Israel controlled these areas: I did not restore this because no source was provided. 
 # Statements that the reports of UNRWA denial that it would teach the Holocaust were inaccurate: I did not restore this because it was not supported by the cited source and is evidently false. There was a disputed quote (see below), but there were several quotes in reliable sources that were never disputed. The disputed quote played no part in the affair, at least no part that was ever recorded in this article. 
 # Deletion of non-disputed reports of UNRWA denial that it would teach the Holocaust: I did not restore this deletion (meaning I kept the reports), because it was unwarranted and an obvious attempt to shore up the previous statement through selective omission of material. 
 # Statement regarding the Simon Wiesenthal Center attribution and UNRWA denial: I restored it and fixed it for accuracy. 
 # Summary of criticism of UNRWA in the Palestine Information Center: I restored this despite the source being unreliable, because it is reliable for its own opinions and those of its writers. 
 # Statement regarding a UNRWA Holocaust exhibit tour for students: I did not restore this because the sources, a blog by academician Rex Brynen and the aforementioned Palestine Information Center, do not seem reliable.
