Dear Diary: I'm strutting my stuff upon the world's stage, here in Cardiff. I have been practicing my Welsh, saying " Yechidda" [Welsh for "cheers"] to greet other NATO leaders so as not to intimidate them with the overwhelming force of my intellect. I am determined to hatch a compromise to the Isis crisis which they will all accept gratefully. What would the world do without Barry? But that's enough about me.
