:The "supplementary" sources were generally non-WP:RS sources, such as tourism sites and fansites, so those are no great loss. Further, a lot of those sites were just used to over-footnote really basic information. No matter how frantically you footnote "Jordan's national dish[1][2][3][4][5]" that doesn't somehow remove the credibility of other reliable sources stating it is found outside of Jordan. 

 :So far as Politicizing a "meal" is not a good idea, it is you and not I who are politicising it. You're trying to turn a cuisine article into a Jordanian propaganda piece, which is just silly. There are tons and tons of gBooks hits for "mansaf Palestine" and "mansaf Syria". If indeed it is only "newly introduced to parts of the west bank" (are you deliberately avoiding the word "Palestine"?) please provide references stating this. So far as the statements that mansaf is used as a political symbol by the Jordanian government, yes it is primarily one anthropologist who's fleshed out a larger argument on that (that I can find on gBooks) but he's widely cited by others. And, ironically, your own editing behaviour seems to bear testament to how politically contentious a simple pile of rice and yogurt is. I fear we're seeing some WP:TIGERS here...
