Can you imagine if war started on the back of that. Historians and scholars poured over documents and scores of books were written on the origins of the First World War. How ridiculous would it be if in 50 years some school kids ask how the war started and the answer is because the moron who ran America sent a provocative tweet that was taken as a declaration of war and so the other nutter launched a missile.
The head of Nato, the foreign secretary of every country in the civilised world and every elected head of government should be on the phone this morning to the White House demanding that this prick stop sending tweets and do diplomacy properly.
