To borrow a famous phrase from another American president, no one should ever misunderestimate the capacity for idiocy of Donald J Trump.
You’d think we’d be used to it by now – but today we’re coming to terms with another Trump travel ban, the embarrassment of which has been amplified by his decision to announce it in a solemn national address on the television; like JFK in the Cuban missile crisis, or Nixon saying he had never been a quitter in his resignation statement.
