The Guardian missed the point about MEK's rehabilitation in US

""The campaign to bury the MEK's bloody history of bombings and assassinations that killed American businessmen, Iranian politicians and thousands of civilians, and to portray it as a loyal US ally against the Islamic government in Tehran has seen large sums of money directed at three principal targets: members of Congress, Washington lobby groups and influential former officials.""  It is none of that.  Simply put: MEK has been performing services for the Mossad and the Mossad has been grateful.  End of story.  See the list of American friends of MEK.
