David Cameron warned today against what he described as an "all-singing, dancing and acting... El Presidente of Europe".
What he wouldn't do was repeat William Hague's alleged warning that a future Conservative government would regard the selection of Tony Blair as president of the European Council as "a hostile act".
Mr Cameron also refuses to say yet what he will do if the Lisbon Treaty is ratified - although there were hints. He spoke of the need for "realism not isolationism" and argued that on every decision in Europe, he favoured "co-operation and co-ordination".
I read this to be not a referendum and not a repeat of John Major's campaign of non-co-operation.
