This chart, delivered by Martin Wolf shows who will suffer from US Tariffs, the answer is

Trump is imposing extraordinarily punitive tariffs on poor countries

But Wolf concludes as Germany’s Kiel Institute argues, the biggest negative effects are likely to fall on the US: protection is usually an own goal.

This doesn’t matter because Trump’s learned how to be Emperor, as Wolf puts it

The debate over whether to take Trump literally or seriously is over. He has now learnt how to be the tyrant he always wished to be.

That took a while. But, with the help he has received, he is there. His administration is engaged in a comprehensive assault on the American republic and the global order it created. Under attack domestically are the state, the rule of law, the role of the legislature, the role of the courts, the commitment to science and the independence of the universities.

All these were the pillars on which US freedom and prosperity rested. Now, he is destroying the liberal international order. Soon, I presume, Trump will be invading countries, as he proceeds to restore the age of empires.

Yesterday I asked the question about whether those living in the USA should consider moving out, especially if they are British by birth. I hope that my generation – and I have several friends who can return- will

There are many liberal people who will have nothing to do with the policies that put the whole world to trouble but America to most trouble. But I hope that those who hold the competency of America, stay. They cannot allow this for the sake not just of the likes of Lesotho and Cambodia but for the USA. As Wolf concludes

So long as Maga dominates the American right, the US potential for unpredictable, irrational and pernicious behaviour will remain. That is, alas, a huge gift to China. But the worse it now gets, the more likely it is that Maga will be an interlude, not America’s destiny. This is a consolation and a hope.

Reform UK , founded and again run by the charismatic Nigel Farage is a similar populist movement. In France , Marie Le Pen has shown her potency. It will be interesting to see whether populist, Maga style, parties – will win support in the light of Trump’s allies in days of yore. Will European and British people support the kind of policies of Trump and his retinue of advisors?

We will find out over the next few weeks and months. My hope is that my friends come back to a Britain which rejects Maga, Trump and considers its global responsibilities as it has ever done. This is why we need to be deadly serious at this time. I have hope.
