It was one of those moments that America thinks is funny – and wonders why the rest of us don’t.
President Ronald Reagan, not realising that the mike he was on was live, joked that he had passed legislation to end the Russian threat forever. The punchline, of course, was “We begin bombing in five minutes.”
Now, there are conspiracy theories aplenty about whether or not he actually knew the microphone was live, but he remained stalwart in his claims that he had not, and that was good enough for most people. It remains an oddity in American politics: a shocking gaffe that probably helped Reagan win re-election later that year.
