That leaves the wise old foreign policy owls. When it comes to unsavoury foreigners, Eagleburger, Scowcroft and Kissinger are all famously “realist”, though there’s a fine line between realism and inertia. A decade ago, Brent Scowcroft advised Bush, Sr to stick with Gorbachev and the preservation of the Soviet Union over Yeltsin and a democratic Russia.

Last autumn, he argued in favour of leaving the Taliban in power. Inevitably Scowcroft now supports letting Saddam be because, if we start a war, “We could have an explosion in the Middle East. It could turn the whole region into a cauldron.”

He says that like it’s a bad thing.
