But how far have they thought it through? The operations risk a lot, will almost certainly not achieve their goals and are already strengthening the enemy.
The Houthis and their Iranian patrons laid a trap and Britain and America have arguably walked, or flown right into it.
The allied aim is to neutralise the threat posed by the Houthi rebel forces against international shipping in the Red Sea, through which a huge amount of oil and goods pass.
Once a rag-tag rebel army, the Houthis are now a fighting force to be reckoned with, dominating much of Yemen and armed and trained by Iran.
They have been attacking ships since the start of Israel’s Gaza offensive in solidarity with their Arab brothers, they say.
The Houthis are hitting the West where it hurts – but to be successful, the British-American airstrikes must entirely neutralise their threat to the Red Sea.

Transport minister Huw Merriman says ‘we are not ruling out further strikes against the Houthis’.
While any threat persists, international shipping must avoid the Red Sea because of the punitive cost of insurance which has in some cases risen 20-fold.
That degree of success is unfeasible. Ask the Saudis who failed to deter the Houthis despite eight years of military action supported by Gulf allies, the UK and the US.
But more to the point, the capability the Houthis are using to threaten shipping is mobile and easily hidden in the desert wastes of Yemen.
The airstrikes will certainly degrade the Houthis.

‘Plucky’ Houthis revelling in popularity
But they only need to continue threatening shipping. For that, the Houthis need to hang on to a handful of portable assets and render the Red Sea unviable as a conduit for international shipping.
And despite everything British and American jets threw at them two weeks ago, they’ve managed to keep up the threat, letting loose missiles at shipping regardless.
Meanwhile the Houthis are benefiting from the military action where it counts for them in the arena of Arab public opinion.
While corrupt, decadent autocratic Arab regimes, as millions of Arabs see them, are doing nothing about Gaza, the plucky Houthis are. And they are revelling in it.

Meet ‘Timhouthi Chalamet’
As Sky News has shown today, the conflict is making celebrities of the Houthis, like the man they are calling Timhouthi Chalamet, a young photogenic Houthi online influencer.
And the Houthis have successfully drawn Britain and America deeper into the Middle Eastern conflict that’s swirling around Gaza.
Rishi Sunak may claim the airstrikes are “unrelated” to Gaza but that’s frankly nonsense. The Houthis have made this explicitly about Gaza. They began their action over the war there and will end it, most analysts agree, once there is a ceasefire.
The British and Americans are letting loose armaments worth tens of millions on one of the world’s poorest countries to allow Israel to do the same in another equally impoverished area.
That is certainly how this is being seen by hundreds of millions.

None of that is any good for either countries’ standing in the Arab world and beyond. It is a PR disaster for Britain and America and a huge boost for the Houthis and by association their Iranian patrons.
The airstrikes may be blowing up bunkers and weapons stockpiles or rearranging sand in the desert but in the battle for hearts and minds across the Middle East, they are handing a victory to Iran and its allies.
And they are almost certainly not going to make the Red Sea a viable international trade route again, not until Israel ends its offensive in Gaza.
The twin threats of climate change and Russian malign activity in the Arctic must be taken “deadly seriously,” David Lammy has warned.
Sky News joined him on the furthest reaching tour of the Arctic by a British foreign secretary.
We travelled to Svalbard – a Norwegian archipelago that is the most northern settled land on Earth, 400 miles from the North Pole.
It is at the heart of an Arctic region facing growing geopolitical tension and feeling the brunt of climate change.
Mr Lammy told us the geopolitics of the region must be taken “deadly seriously” due to climate change and “the threats we’re seeing from Russia”.
We witnessed the direct impact of climate change along Svalbard’s coastline and inland waterways. There is less ice, we were told, compared to the past.

The melting ice is opening up the Arctic and allowing Russia more freedom to manoeuvre.

“We do see Russia’s shadow fleet using these waters,” Mr Lammy said. “We do see increased activity from submarines with nuclear capability under our waters and we do see hybrid sabotage of undersea cables at this time.”
In Tromso, further south, the foreign secretary was briefed by Norwegian military commanders.

Vice Admiral Rune Andersen, the Chief of Norwegian Joint Headquarters, told Sky News the Russian threat was explicit.
“Russia has stated that they are in confrontation with the West and are utilising a lot of hybrid methods to undermine Western security,” he said.
But it’s not just Vladimir Putin they’re worried about. Norwegian observers are concerned by US president Donald Trump’s strange relationship with the Russian leader too.

Karsten Friis, a Norwegian defence and security analyst, told Sky News: “If he’s too soft on Putin, if he is kind of normalising relations with Russia, I wouldn’t be surprised.
“I would expect Russia to push us, to test us, to push borders, to see what we can do as Europeans.”
Changes in the Arctic mean new challenges for the NATO military alliance – including stepping up activity to deter threats, most of all from Russia.
In Iceland, we toured a NATO airbase with the foreign secretary.
There, he said maintaining robust presence in the Arctic was essential for western security.
“Let’s be clear, in this challenging geopolitical moment the high north and the Arctic is a heavily contested arena and we should be under no doubt that NATO and the UK need to protect it for our own national security.”

A British charity has written to the prime minister and foreign secretary, urging them to allow seriously ill children from Gaza into the UK to receive life-saving medical treatment.

The co-founder of Project Pure Hope told Sky News it was way past the time for words.
“Now, we need action,” Omar Dinn said.
He’s identified two children inside Gaza who urgently need help and is appealing to the UK government to issue visas as a matter of urgency.
Britain has taken only two patients from Gaza for medical treatment in 20 months of Israeli bombardment.

“Most of the people affected by this catastrophe that’s unfolding in Gaza are children,” he continued. “And children are the most vulnerable.
“They have nothing to do with the politics, and we really just need to see them for what they are.
“They are children, just like my children, just like everybody’s children in this country – and we have the ability to help them.”
Sky News has been sent video blogs from British surgeons working in Gaza right now which show the conditions and difficulties they’re working under.
They prepare for potential immediate evacuation whilst facing long lists, mainly of children, needing life-saving emergency treatment day after day.

Dr Victoria Rose told us: “Every time I come, I say it’s really bad, but this is on a completely different scale now. It’s mass casualties. It’s utter carnage.
“We are incapable of getting through this volume. We don’t have the personnel. We don’t have the medical supplies. And we really don’t have the facilities.
“We are the last standing hospital in the south of Gaza. We really are on our knees now.”
One of her patients is three-year-old Hatem, who was badly burned when an Israeli airstrike hit the family apartment.

His pregnant mother and father were both killed, leaving him an orphan. He has 35 percent burns on his small body.
“It’s a massive burn for a little guy like this,” Dr Rose says. “He’s so adorable. His eyelids are burnt. His hands are burnt. His feet are burnt.”
Hatem’s grandfather barely leaves his hospital bedside. Hatem Senior told us: “What did these children do wrong to suffer such injuries? To be burned and bombed? We ask God to grant them healing.”

The second child identified by the charity is Karam, who, aged one, is trying to survive in a tent in deeply unhygienic surroundings with a protruding intestine.
He’s suffering from a birth defect called Hirschsprung disease, which could be easily operated on with the right skills and equipment – unavailable to him in Gaza right now.

Karam’s mother Manal told our Gaza camera crew: “No matter how much I describe how much my son is suffering, I wouldn’t be able to describe it enough. I swear I am constantly crying.”
Children are among the bulk of casualties – some 16,000 have been killed, according to the latest figures from local health officials – and make up the majority of those being operated on, according to the British surgical team on the ground.
