Where is the responsibility of the Vatican which signed the concord with Hitler in 1933 giving him tremendous prestige? Are we not to find the Vatican guilty?
Where is the responsibility of a Royal Chapter of Her Majesty's government, which said in an open letter to the Los Angeles Times in 1938, [pointing in finger in the air] In1938! "In the event of natural disaster we should pray to god to send a man of the strength of mind and will of Hitler.' Are we not to find Winston Churchill guilty?
Where is the responsibility [voice rising] of those American industrialists, who helped Hitler create his government? Are we not to find the American industrialists guilty?
[shouting] No! Your Honor. It is an easy thing to condemn the German people - to speak of a basic flaw in the German character that allowed Hitler to rise to power. [loudly and slowing with emphasis] The whole world is responsible for Hitler's Germany! "
(When Hitler invaded Poland ever major US corporation from GE and GM to ITT, IBM, Coca Coal etc. were joint venturing in Germany. GM, GE, Ford, Dupont and ITT actually owning factories building army vehicles and war planes.) [see footnote]
To describe only one such distinguished American investor in Hitler:
The Head of the Hitler Youth had testified that German translations of Henry Ford's The International Jew were required reading for all new recruits. Ford was Hitler's earliest backer and received a decoration from Hitler, who had Henry's photo on his wall.
It was Ford's funds (reported to be as high as $70,000) that helped finance Hitler's failed Bavarian rebellion in Munich. During Hitler's trial it was discovered that Ford's associates came in contact with Hitler's mentor Dietrich Eckart while trying to sell Germany tractors. Eckart asked for financial aid and got it almost immediately from Ford. Four days following Hitler's release from Landsberg prison, Hitler stayed at the home of a wealthy friend where he received a new copy of Mein Leben und Werk (My Life and Work) by Henry Ford, a book he would revere and read carefully. 
In 1928 Ford merged his assets with I.G. Farben, the German chemical cartel, which strengthened the Nazi cause further. Hitler told a Detroit News reporter that he regarded "Henry Ford as my inspiration." Ford supported Nazis until his position made him treasonous.
To show his appreciation for Ford's similar hatred toward Jews, Hitler awarded Henry Ford the Grand Cross of the German Eagle, a Nazi citation reserved for foreign men of distinction. It was presented to Ford on his 75th birthday in his Dearborn office. The award brought immediate concern from Jewish leaders, which led Ford to say that his acceptance of the medal did not mean he had sympathy for Nazism, and he was a person who was repulsed by anything that bred hate. The same kind of medal was given to the head of IBM (who returned it) and American aviation hero Charles Lindbergh, who was haunted all his life by his pre-war pro Nazi statements. Henry Ford never returned the medal though Secretary of the Interior Harold Ickes denounced its acceptance publicly. 
Today the most powerful and respected institutions in America are The Ford Foundation, The Rockefeller Foundation, the Chase Bank. [The Rockefeller Family invested heavily in both world wars and prospered beyond imagination - John Rockefeller's New Jersey Standard Oil was prosecuted in 1945, for having made a fortune selling oil to Nazi Germany through subsidiaries in South America.]
This writer has no doubt that our colleague Swanson had the best of intentions in calling for the prosecution of presidents, as had been called for before with Bush, Johnson, Nixon and even Truman during the Korean police action, but to no avail. It could only be a step in the right direction, if David means it as a taking off point for a broader call for indictment of Americans.
There is an atmosphere of pretended and unjustified innocence that seems to pervade the US peace and justice or antiwar movement, which, continually points a finger away from those who are protesting and instead at the very own government of the protestors. Martin Luther King dismissed his government as the greatest purveyor, not cause, but purveyor, of violence in the world, while, in anguish, holding America, Americans, including himself, responsible and not America's own elected and reelected public servants which he directed not a single word to in his entire sermon Beyond Vietnam.
The more than ten million survivors of American genocide hold all Americans responsible before the law, including protestors of American crimes as if they were merely mistakes in foreign policies. They were not mistakes, and leaders like David, I'm sure will soon stop this kind of misleading exposing of crimes without calling for punishment of all those who commit them.
King held himself and his American audience responsible for being perfectly capable of making these atrocity wars for profit unacceptable and inoperable through non-participation, non-support, non-acquiescence and conscientious objection.
Secondly, the whole US peace movement is flat-out against King's insisting that the killing must be stopped first. For every bit of attention given to the wars by leading alternate media journalists like David, there are many more articles about every possible injustice being suffered by Americans from other Americans, in spite of Martin Luther King making it thunderingly clear that not only for moral reasons but for damned simple logic, Americans killing the poor overseas must be stopped firstly, for "the obvious massive expenditure of human and financial resources makes any progress on social justice at home impossible."
