Washington ( CNN ) -- Among the volumes of diplomatic communications released by WikiLeaks are frank observations about the character of world leaders , their quirks and their weaknesses . In an initial review of the documents turns up a number of observations from U.S. staffers that provide unusual insight into foreign leaders ' thinking and behavior , from `` voluptuous '' companions to attention-seeking personalities . Saudi Arabia 's King Abdullah proposed to U.S. officials that a Bluetooth-like device be implanted in Guantanamo detainees . During a March 22 , 2009 , meeting between Deputy National Security Adviser John Brennan and King Abdullah , the king suggested that an `` electronic chip '' would allow the tracking of the detainees ' movements , as with Saudi horses and falcons . Brennan deflected the idea , saying that `` 'horses do n't have good lawyers ' and that such a proposal would face legal hurdles in the U.S. '' Another communication dated February 10 said the Saudi king `` tends to express himself tersely '' because of his lifelong struggle with a `` speech impediment '' but added that he is a `` wry and forthright interlocutor . '' The foibles of Libya 's leader get a lot of attention in a cable from the American Embassy in Tripoli . Under the subject line `` A glimpse into Libyan leader [ Moammar Gadhafi 's ] eccentricities , '' there is an extensive discussion of his `` various proclivities and phobias '' and his almost obsessive reliance on his nurse , a woman described as a `` voluptuous blonde . '' The document goes on to detail the relationship between the 38-year-old Ukrainian nurse , Galyna Kolotnytska , and Gadhafi , touching on rumors of a romantic relationship . It also discusses the lengths the Libyan leader will go to ensure that Kolotnytska travels with him , saying that only she `` knows his routine . '' The cable says Gadhafi is `` almost obsessively dependent on a small core of trusted personnel . '' Also among his quirks : Gadhafi 's dislike of flying long distances , his fear of flying over water and his need to stay on the first floor of any building . These diplomatically embarrassing cables extend beyond the Middle East and North Africa . They include observations from around the world , including Europe and longtime allies Germany , France and Italy . Of French President Nicolas Sarkozy , one cable gave this open assessment : `` An activist on the international scene , with an opportunistic eye for grabbing attention and credit , Sarkozy will remain a challenging partner despite his desire to improve the bilateral relationship . '' Some news outlets have reported that U.S. diplomats called Sarkozy an `` emperor with no clothes . '' On Italy 's Prime Minister Silvio Berlusconi and his relationship with Russia : The Italian leader `` appears increasingly to be the mouthpiece of [ Prime Minister Vladimir ] Putin , '' according to a report from the New York Times . Regarding German Chancellor Angela Merkel : `` When cornered , Merkel can be tenacious but is risk-averse and rarely creative . This suggests she will remain a very circumspect ally until the election . '' Although these cables may provide the U.S. with some uncomfortable moments with global partners , they are not limited to foreign leaders . American officials are also a topic of discussion . An almost prescient communication dated February 10 talks about the fallout from Gen. Stanley McChrystal 's interview with the German news outlet Bild ; four months later , his controversial interview with Rolling Stone was published , and he was forced to resign as head of the mission in Afghanistan . German Foreign Minister Guido Westerwelle asked to express his concerns `` confidentially '' about McChrystal 's interview . According to the cable , Westerwelle was particularly worried about a portion of the interview `` in which the general is quoted as urging the Germans to take more risks . Westerwelle recounted that he himself had to answer questions about this article for 10 days , explaining that the Germans were not 'peace soldiers ' while other countries provided combat troops . '' Westerwelle went on to stress that it was `` important that German troops not be 'relativized ' and cast as second-class troops . '' Another document paints Westerwelle in a less than flattering light , noting that the foreign minister , ironically , `` has never harbored a fascination for international affairs . ''
