As JFK noted in his Ich bin ein Berliner speech, "Two thousand years ago, the proudest boast was 'civis Romanus sum.'" [I am a Roman citizen.] A Roman enjoyed the rights and privileges of his citizenship wherever he traveled, cloaked in the mantle of Roman law and might even in distant lands.
Has citizenship fallen so far that a former American president can be hounded and exiled from the wider world by threats of imprisonment in foreign lands for actions taken while presiding in office? Is America so low in estimation to the respect once due to Rome?
It seems likely that George W. Bush was forced to cancel a visit to Switzerland for fear that he would be arrested and tried for war crimes in a foreign court. Such threats have been made against other Bush administration officials, CIA agents, Donald Rumsfeld and Henry Kissenger (who has actually fled threatened abduction and prosecution abroad).
That American citizens must fear to travel abroad, lest foreign powers exert control over their liberty and judge them for acts of political administration in the United States is so far from acceptable as to provoke open hostilities on the national stage. David Frum correctly chides Obama for not protesting such a threat upon his predecessor (which he would also have reason to fear for drone attacks in Pakistan, were he not the darling of the leftist rabble raising such threats). Switzerland ought also to answer for the threat, clearly extending it's welcome to American citizens and assuring them of safe passage.
"Universal jurisdiction" is an attack upon national sovereignty to which the United States has not succumbed. It is not rule of law, but rule of the defeated and discontent. The world must be made to know that the mantle of American law and might protects her citizens in every land known to man.
