John Howard in a paragraph

Yes, but when it comes down to it he's not hugely relevant so is ignorable internationally - his government has pretty well been in caretaker mode for the last decade and his foreign policy is "me too". Even a major US newspaper got his name wrong and called him Mike Hunt when he was visiting the USA - possibly misled by an Aussie that was playing a bit of a joke. The last Prime Minister we had that we would expect people to notice is Malcolm Fraser - very tall, face like an Easter Island statue and memorable for running around in a US hotel with no pants on.
