I did not add any new information. I updated references and cites. The article was listed in a category of CS1 maintenance warning/errors. I try to fix the problem and any others I find. This article also had bare URLs and dead links. I often add a "use ___ dates" template and remove df= and language=en. Nuclear weapons and Israel still has Category:Harv and Sfn no-target errors errors. I use the "Trappist the monk" script documented in the category page to display the errors. They probably were created when an editor cut and pasted information from another Wikipedia article and did not copy the source cites. Using "op. cit." is also deprecated and I added SFN templates for these refs to highlight them. Somebody will appreciate complete source cites added to the Bibliography section.
