In today’s newsletter: Pjotr Sauer explains Russia’s response to the new Trump administration following a fraught week in global relations

Good morning. In his address to Congress last night, Donald Trump recited a letter from Volodymyr Zelenskyy offering to return to the negotiating table – and warmly welcomed the tone of discussions his administration has held with Russia. “We’ve received strong signals that they are ready for peace,” he said. “Wouldn’t that be beautiful?”

That was not the first sign of Trump’s faith in Vladimir Putin’s promises – but it served to underline what is surely the most radical US foreign policy shift in a generation. Whether parroting Kremlin talking points on Zelenskyy’s democratic credentials, making false claims that Ukraine started the war or cutting off vital military aid to Kyiv, the US president has created a dynamic that would have scarcely been believable six months ago.

Killed women count | Nearly one in 10 of all women who died at the hands of men in the UK over the past 15 years were mothers killed by their sons, a report reveals. The statistics have led to calls for the government to take specific action to tackle matricide.

Tariffs | Justin Trudeau has claimed the aim of a “dumb” trade war launched by Donald Trump is to usher in the “complete collapse” of the Canadian economy and make it easier for the US to annex Canada. Leading stock market indices fell sharply, with the US benchmark S&P 500 losing all its post-election gains, as the US slapped 25% taxes on Canadian and Mexican goods and hiked tariffs on China.

Scams | An organised network operating from the former Soviet state of Georgia has scammed thousands of savers from the UK, Europe and Canada out of $35m (£27m) after they fell for fake celebrity adverts on Facebook and Google. The scheme was revealed in a leak of call centre data covering more than 1m recordings.

Gaza | Arab leaders have endorsed a $53bn (£42bn) plan to rebuild Gaza under the future administration of the Palestinian Authority (PA), in a rushed attempt to present an alternative to Donald Trump’s idea for a property development-style plan. The Arab League presented the plans at a summit in Cairo.

Media | Failings in the making of a documentary on Gaza are a “dagger to the heart” of the BBC’s claims of trustworthiness and impartiality, the corporation’s chair has said, as he indicated that figures inside the corporation had fallen short in their handling of the film.
