but at the same time it will be paying Venezuela for this oil. It's still very much up in the air where this money is going to go, who this investment is going to come from and crucially when it's going to happen.

Nick Marsh there. And it's not just Venezuela that the US has in its sights. The US Secretary of State Marco Rubio says he'll hold talks with Denmark next week about the future of Greenland. Donald Trump recently said he was considering using the military to take it by force. Denmark, which has control over Greenland's foreign and defence policy, has warned that any attack could see the end of the NATO military alliance. So why does President Trump want the territory? A question for our diplomatic correspondent James Landell.

No, jos katsot maan, niin Arktikki on tärkeä geopoliittinen maatilanne. Ja kun maatilanne kääntyy, Trump kertoo, että maatilanne on rauhoittumassa russien ja chinesien kaupojen kanssa. Mutta se ei ole vain turvallisuudessa. Greenland on myös pakkannut valitettavissa luonnonmuutoksissa, joilla on öljy ja kriittiset mineralit, joita amerikkalaiset haluavat.

Ja uusi Yhdysvallan valtion turvallisuusstrategia käsittelee myös Trumpin uskoa, että Yhdysvallat pitäisi voida vahvistaa, mitä hän kutsuu väestön hemisfeeriin. Ja se tarkoittaa sydäntä sekä sydäntä. Joten mitä presidentin vaihtoehtoja on? No, Yhdysvallat voivat vahvistaa capital nuke, vaikka Denmarkissa ei ole kauhean mitään sääntöjä.

Olemme puhumassa poliittisesta teatterista. Voi olla, että yksi poliittinen johtaja voisi mennä nukkumaan ja sanoa, että Greenland on nyt Yhdysvallojen oma. Ei ole vahvistusta, jota heidän pitäisi vahvistaa. Ei ole paikallista, jota heidän pitäisi vahvistaa.

European leaders warned this week that any military action would fundamentally damage the transatlantic alliance. But today Mr Trump hit back, saying he doubted his NATO allies would be there for the US if it really needed them. We will always be there for NATO, he said, even if they won't be there for us.

So if military action is less likely, what else? Well, the US could buy Greenland, something the White House says is actively being considered. America's top diplomat says he'll discuss options with Danish officials next week.

A third option would be to offer the people of Greenland a special association agreement where the US would control their defence and they in return would get economic support. As for a fourth option, well, the US already has an airbase in Greenland. It could simply send thousands more troops under an existing military deal. But for now, the US seems to want this arctic snowscape for its own, whatever the cost.

There you'll find more analysis on whether President Trump would use military force to take control of Greenland. And there's a new story available every weekday. So what does all of this mean for America's role in the world and for everyone else? I asked our international editor Jeremy Bowen for his assessment.

Hän oli vastuullinen noin 10 henkilöä, jotka olivat valmistuneet. Hän haastoi noin 20 yksilöä, jotka olivat haastattuja. Hän eläi moraalisessa kärsivässä. CIA's worst ever traitor has died at the age of 84.

New data published in the British Medical Journal suggests that people who stop taking weight loss jabs can put the pounds back on around four times faster than if they'd been dieting and exercising. The research from the University of Oxford was led by Professor Susan Jebb. She's been speaking to our health reporter Jim Reid.

What this research has shown is these drugs are really helpful in losing weight, but they're not a silver bullet. They're not a magic solution forevermore. When people stop the treatment, the weight goes back on surprisingly quickly. So you really need to think about these as part of a much longer term strategy to help you control your weight. One of the messages that came through is that people on these kind of drugs are going to need more support to come off them.

Whilst people were taking these weight loss medications, those people who also had a good behavioural support programme, helping them to reset their diet and physical activity, actually were much more successful and they lost four and a half kilos more weight than those people who didn't have that extra support.

Toivottavasti tuotantosuunnitelma, jossa he olivat käyttäneet taitoja, ei näyttänyt pysyä heitä vähemmistöön myöhemmin. Se tarkoittaa, että jos huolehtiminen pysyy, ihmiset tarvitsevat jotain muuta autta. Nyt en tiedä, mikä on paras vaihtoehto, mutta on paljon tutkimusta, jotta voimme antaa ihmisille avustusta, miten paremmin pysyä vähemmistöön myöhemmin.

Can I ask you one question about what your research showed around the other markers to your health and how quickly they returned to baseline? Because this wasn't necessarily just about weight, right? This was about cardiovascular and other issues. So when people lose weight, we see that all the risk factors for heart disease improve quite markedly and very quickly. So blood pressure comes down faster.

Blood glucose control improves, cholesterol reduces. And that's fantastic news because it's what helps improve your health and reduce your long-term chances of heart disease. However, perhaps unsurprisingly, if you put weight back on, then those problems return. So we really do need to find a way of consolidating that weight loss in order to also preserve those long-term health benefits too.

You mentioned it's not a silver bullet for individuals. Presumably the same thing would go for the health service here. And there was some suggestion that this might not be as cost effective as potentially some people might hope.

For people with severe and complex obesity, these treatments really are incredibly important, and they're going to be a very good way to help them improve their health, but they may well need to be continued long term. For people with less severe obesity, it's questionable whether these will be cost effective, and what we should probably be doing is really ensuring we give other people access to other

Kiitos.

Professor Susan Jebb, and her study comes as separate research from University College London and the University of Cambridge, found that people prescribed the new generation of weight loss drugs may be vulnerable to nutritional deficiencies and muscle loss.
