If elected (bet on the snowball in hell beating him) the Joe-McCarthy-look-alike-Teabagger Wingnut Senator Ted Cruz will be stepping into arrestable grounds.
Ted Cruz said Friday at the Value Voters Summit conference in Washington, D.C., “If you vote for me, under no circumstances will Iran be allowed to acquire nuclear weapons. And if the ayatollah doesn’t understand that, we may have to help introduce him to his 72 virgins.”
We'll skip the irony of this gathering of PartyofNoicans being labeled "Value Voters".
It would appear the rabble-rousing Senator is ignorant of the 1978 law, banning political assassinations.
Executive Order 11905 is a United States Presidential Executive Order signed on February 18, 1976, by President Gerald R. Ford as an attempt to reform the United States Intelligence Community, improve oversight on foreign intelligence activities, and ban political assassination. Much of this EO would be changed or strengthened by Jimmy Carter's Executive Order 12036 in 1978.
This came about from the post-Watergate mop up of National Criminal President Richard M. Nixon's enterprise, led by the Church Committee, of Senator Frank Church (D-ID), or the United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities.
If the Idiot Senator was only joking ...
Well, considering the United States' history of assassinating World Leaders, and the need of Executive Order 11905 (which was reaffirmed by both Presidents, Carter and Reagan), it's not something to boast about as your qualifications for the Office of President.
Best advise I can offer to the threatened Ayatollah Khamenei is to Google Senator Ted Cruz, and have yourself a good laugh.
