When Americans voted, by a narrow margin, for Donald Trump in November, the British rolled their eyes.

Trump was, so many of us thought, a boorish outsider who lacked judgment and who had never held office. We would never make such a mistake as that made by our foolish cousins across the Pond, or so we thought.  

Today, Britons woke up to the news that the Conservative Prime Minister, Theresa May, had somehow lost her parliamentary majority. Having called a snap election to capitalize on her political opponents’ perceived weaknesses and in the expectation of an increased parliamentary mandate to help her deliver Brexit, May contrived to turn a commanding 24-point poll lead into a narrow two-point advantage.  

The leader of the Labour Party, Jeremy Corbyn – a man who whose extreme views make Bernie Sanders seem sane – did sufficiently well to be able to claim that, despite not winning the popular share of the vote or even a majority of seats in Parliament, he was the moral victor in the election.  

The 68-year-old Corbyn has applauded the evil totalitarian regimes of Chavez in Venezuela and Castro in Cuba. He praised Irish republican terrorism even while IRA bombers killed innocent civilians and servicemen on the streets of Britain (and tried, thankfully without success, to murder Margaret Thatcher). He has called Hamas his "friends." He tolerates anti-Semitism with worrying regularity even among those closest to him.  

He has opposed every single measure aimed at strengthening security and enabling the security services and police to defeat Islamic terrorism. He supports state ownership of utilities and confiscatory levels of taxation on the middle classes.  

How has this swivel-eyed extremist found himself so close to power? Here, simply, is what went wrong:  

Thank God for Scotland and Northern Ireland. Having under-performed in England, the Conservatives won well in Scotland thanks to their opposition to Scottish independence.  

But 318 MPs still left the Party short of a parliamentary majority. Northern Ireland’s Democratic Unionist Party’s 10 MPs have ridden to the rescue. These socially conservative supporters of Brexit, who passionately want Northern Ireland to remain part of the United Kingdom, are natural bedfellows for the Conservatives. Their support means that May can command the slimmest of parliamentary majorities.  

Brexit will still be delivered. The Special Relationship with the United States remains safe. And a Marxist has been kept from 10 Downing Street by the narrowest of margins.
