It is a shame to see that this so-called encyclopedia is used for political purposes. 

 Actually, everyone is trying to put its own statistics and opinions without any proof or valid source. The sources themselves are often political (from CIA or other dummy spreading organisms). Why not using data from the Chinese secret services then about their Tibetan minority???? 

 Honestly, if the administrators of this website have some honour and aren't politicaly or pecuniary motivated, they should: 
 - forbid the addon of any statistic, "quotation" or comment without a non political and strong source 
 - forbid some sentences turned more like rumours 
 - clean the article, full sometimes of grammar errors... 
 - manage to gather good sources about Iran and all other topics in general 
 - forbid changes by spammers and other people more concerned about their personnal views rather than the continuity of the wiki project 

 Do it guys, you are loosing credibility... And this is a hard thing to recover.
