It’s easy for the British to insult Donald Trump – but here’s why it’s a very bad idea | Simon Jenkins

Is it wise for Britons to heap abuse on Donald Trump? At present he is the marginal favourite to win next week’s US presidential election – with Britons strongly behind his opponent Kamala Harris. But is overt hostility sensible?

Most recent polls show two out of three Britons want Harris to win, including a majority even of Conservatives. The Labour party sent about 100 activists to aid Harris in some swing states. The UK media is almost universally hostile, calling Trump crass, illiterate, vulgar, coarse and fascist. He is identified with the Heritage Foundation’s authoritarian Project 2025, which he has disowned. Only Reform UK is for Trump. Surely dignity would counsel respect for an ally’s internal democracy, and caution in alienating the leader of Britain’s most powerful ally.

First, what’s new? Britain’s Labour and the US’s Democratic party have bonded for decades, including canvassing and attending each other’s conferences. As a student I once campaigned for Mayor Lindsay in New York, and I have a free tie to prove it. The US has itself interfered in Latin American elections since time began. Russia interfered on Trump’s behalf in 2016, with Operation Lakhta, though Trump denied it. Moscow blatantly interfered in elections this month in Moldova and Georgia.

A different question is whether it is wise. Americans can refer to Trump as a fascist, but such facile parallels do little beyond enraging their subjects. More to the point, British opinions on the matter are more likely to evoke the reaction of “mind your own business”. Trump’s first term of office might have had its alarming moments, but the US constitution saw him off – just – and may yet do so again.

In 2017, Trump welcomed the British prime minister, Theresa May, to the White House, and rather endearingly held her hand. The British press sniggered. When the BBC asked him a viciously biased question, claiming to represent “our viewers”, he was able to laugh it off. In the same outgoing spirit, he invited Keir Starmer to dine with him for two hours last month and congratulated him on his election success. These may be merely the courtesies expected of public figures, but Trump adhered to them.

American presidents are complicated. They are political leaders, but they are also heads of state. Diplomatic custom accords them a certain dignity. In Trump’s case, diplomacy must tilt in the same direction. Britons were annoyed when Barack Obama expressed a strong opinion on the side of remain in the Brexit referendum. But when Boris Johnson sought a trade deal in Washington to compensate for withdrawing from the EU single market, he got short shrift. Trump is threatening to go a step further and impose a punishing 10% tariff on all British exports to the US.

This is something Starmer could well do without. He is proposing to penalise American non-doms in Britain in the budget. He may also need to react to a Trump withdrawal of US aid to Ukraine, and his demand for a step-change in British defence spending. Other things being equal, personally insulting the president in such circumstances seems plain stupid.

Trump represents a periodic surge in US rightwing populism. It is a turning against the supposedly liberal east- and west-coast governing elites. Its politics is proletarian, xenophobic, protectionist and conservative. This may not be to every Briton’s taste, though Britain saw a similar surge in Reform UK’s vote at this year’s election, disguised by it splitting a Conservative majority vote.

Such results are the privilege of the franchise. Liberal democrats can bewail them, but they must respect the winners – even if the losers sometimes do not. They must also treat with the winners in the rough and tumble of international politics. Ostracism is never the answer. Disrespecting the outcome of democracy is the shortcut to disaster.
