FarNorth that man is representing you, me and everyone else to the rest of the world - and he is an oaf. I do not want to be represented by someone whose opinion of themselves seems to be well above anyone else's opinion of them and who goes abroad for Great Britain and insults people.
The 'keep you friends close, etc.,' is true in some instances but not all. It can just be an easy, trite saying just as 'Forgive your enemies, but never forget their names.' can be - particularly if they change their names
.
The friend and enemies, close and closer quote is often attributed to Sun Tzu but he said a great deal more than this. For example:
"... but the opportunity of defeating the enemy is provided by the enemy himself."
We can only hope. What Sun Tzu does not do is stop at keeping your enemy closer. If the enemy remains an enemy he talks about how to crush him so the oaf has been kept closer but more now needs to be done before he completely wrecks the opinions held abroad by other countries.
