Smart diplomacy got Putin buzzing our planes, nukes for Iran and the rise of the Islamic State.
But of course none of that matters to Luce. None of the cool kids like Trump. While Luce's own country is overrun by hordes of Muslims raping white British children, Luce is trying to tell us we should stay the course because Trump - somehow -- poses a danger.
Yet it is rash to dismiss Mr Trump’s policies as hopelessly confused. He offers a legitimate contrast to Mrs Clinton. Her campaign will talk of the nitty gritty of making globalisation work for ordinary Americans. He will pound on “the false song of globalism”. She will vow to safeguard human rights. He will promise tougher deals on nationalist grounds.
There is a philosophical difference. As Peter Beinart, former editor of the liberal New Republic, pointed out, Mr Trump did not once refer to “freedom”, “liberty” or “tyranny” in last week’s speech. His only use of the word “dictator” was to scold the US for overthrowing one in Libya. It was Mrs Clinton, of course, who championed that.
As ever, the temptation will be to mock Mr Trump and implicitly disrespect his supporters. So far that has not worked out very well. Mr Trump can, and should, be heavily defeated in November. His victory would deal a huge blow to the US’s standing. But mistaking his demagogic savvy for idiocy is no way to go about it.Of course, Gadhafi was a toothless lion who posed no threat to anyone, however oil interests convinced Tony Blair that Gadhafi must go and Blair convinced Clinton Gadhafi must go and Obama did not want to appear emasculated. So Gadhafi is gone and now the gates of hell are open in Italy as Libyans invade.
The only people hopelessly confused are those who still believe in smart diplomacy. They are the heirs to the pundits who said Reagan would start World War III.
The United States' standing in the world now is that of a dangerously foolish and leaderless superpower adrift at sea, and unaware that it is lost.
