The Washington Post went through an entire article without anti-Israel bias, only to succumb on the last sentence because it just couldn't resist the temptation.  In "Palestinian President Abbas was once a KGB spy, report claims" (09/09/16), the last sentence states that Mahmoud Abbas "spent time in Moscow as a student and wrote his doctoral thesis on the Holocaust while studying there." 

Abbas didn't write his doctoral thesis "on" the Holocaust.  He wrote against the concept of the Holocaust.  Even The NY Times wrote, "Mr. Abbas has been vilified as a Holocaust denier because in his doctoral dissertation, published as a book in 1983, he challenged the number of Jewish victims and argued that Zionists had collaborated with Nazis to propel more people to what would become Israel" (Mahmoud Abbas shifts on Holocaust [04/26/14]).  Further, according to Israeli publication Arutz Sheva ("Report: Abbas' Holocaust-Denial Dissertation Widely-Taught in PA" [04/28/11]), Abbas's dissertation "downgrades the number of Holocaust victims to '[possibly] below one million,' and accuses Zionist leaders of encouraging the persecution of Jews. It also denies that the gas chambers were used to murder Jews, quoting a 'scientific study' to that effect by French Holocaust-denier Robert Faurisson."

Saying that Abbas wrote his doctoral thesis "on" the Holocaust is like saying that Adolph Hitler merely wrote his anti-Semitic manifesto Mein Kampf "on" Jews.
