Hello and welcome to NewsHour. It's coming to you live from the BBC World Service studios in central London. I'm Tim Frags.

It is perhaps not a surprise. It is still stunning to look around and see the number of people who are saying this is a historic shift.

What Donald Trump has said and done in the last 24

hours about a Ukraine-Russia peace deal, how all this presages a huge change not just for Ukraine,

but for the whole of Europe and the way we think about big power politics. Some say these

changes are comparable to events leading up to

and then the aftermath of World War II. Kaya Kallas is the European Union's foreign policy chief,

and what she had to say today in Brussels sounded like a strongly worded retort to any idea of

Washington and Moscow foisting a peace deal on Ukraine or Europe.

It is clear that any deal behind our backs will not work.

Any agreement will need also Ukraine and Europe being part of it.

And this is clear that appeasement also always fails.

That word, appeasement, is hugely loaded, redolent as it is, of the failed attempt ahead of World War II

to contain Hitler's continental ambitions.

Meanwhile, also in Brussels, there's been strong language from the U.S. Defense Secretary Pete Hexeth,

aimed at the European partners of the decades-old Transatlantic Security Alliance, NATO.

After World War II, Eisenhower, was one of NATO's strongest supporters.

However, by the end of Eisenhower's presidency, even he was concerned that Europe was not shouldering enough of its

own defense, nearly making, in Eisenhower's words, quote, a sucker out of Uncle Sam. This administration

believes in alliances. But make no mistake, President Trump will not allow anyone to turn Uncle Sam into Uncle Sucker.

Tough language all round at the NATO Defence Minister's meeting.

The BBC's Jonathan Beale has spent the day there.
