The race to prepare for the battle of the Donbas is on, with Russia shifting its troops, materiel and objectives to the eastern region of Ukraine, and the U.S. and its allies rushing in weaponry to equip Ukraine’s forces.

The big picture: In the first phase of the war, Russian troops attacked across three broad fronts, hoping to quickly take cities (including Kyiv), but they became over-stretched and suffered heavy losses. Russia is pulling tens of thousands of those troops back and preparing them for a narrower and potentially decisive fight for the Donbas.

• Russian President Vladimir Putin has said that peace talks are at a dead end, and Moscow’s focus will now be the “liberation” of all of the Donbas, about one-third of which was controlled by Russian-backed separatists prior to his Feb. 24 invasion.
• Putin justified the invasion in part through erroneous claims of a “genocide” against Russian speakers in the Donbas — a claim undermined by the fierce resistance put up by civilians in largely Russian-speaking cities like Mariupol.
• That city, the third-largest in the Donbas after Russian-held Donetsk and Luhansk, could be within days of falling to Russia after seven weeks of brutal bombardment. That would give Putin a much-needed symbolic victory, and free up more Russian forces for the coming offensive.

The battle for the Donbas will remove some of the obstacles Russian forces struggled with elsewhere in the campaign.

• It’s largely flat and wide open, unlike the more urban terrain near Kyiv. That’s ideal for Russian artillery and tanks, though rains have made much of the ground muddy.
• Russia should have fewer supply line issues fighting so close to its own territory, and fewer organizational and communications challenges in a more concentrated fight.

Yes, but: Manpower and morale are both obstacles. It will take time to properly reorganize and redeploy so many units given the heavy losses Russia has suffered, says Michael Kofman, a top expert on Russia’s military at CNA. Large numbers of reserves aren’t expected anytime soon.

• Ukrainian forces have also dug in across much of the region through eight years of war, and they'll likely be fortifying towns and laying mines to further slow the Russian advance, he says.
• Kofman thinks Russia’s commanders would be wise to delay their offensive until they’ve had time to fully build up their force, rather than “repeat the errors from earlier in the war.”
• But that will also leave time for Ukraine’s Western partners to supply additional heavy weaponry.

What to watch: Concerns in Washington and some European capitals that Moscow would view shipments of certain offensive weapons as overly “provocative” have largely faded, Axios’ Zach Basu reports.

• The $800 million package President Biden announced yesterday includes helicopters, artillery systems and armored vehicles.
• Ukrainian President Volodymyr Zelensky pressed for more in his latest video address, saying, "Freedom must be armed better than tyranny."

The latest: Russia also suffered a major blow today on the 50th day of war: the Moskva cruiser, the flagship of its Black Sea fleet, has sunk. It's the largest military vessel to sink in decades. Go deeper.

During the most parochial of domestic crises, Boris Johnson is making global headlines with his plans to send heavy weaponry to Ukraine and asylum-seekers to Rwanda, Axios' Zach Basu writes.

Why it matters: We've entered a whiplash-inducing phase of the ongoing debate about whether Brexit has produced "Global Britain" or "little England." On support for Ukraine, Johnson truly has been a global leader. But at home, he's lurching from one crisis to the next.

State of play: Johnson this week became the first sitting prime minister in British history to be fined for breaking the law. But he currently looks set to survive the scandal over parties held in Downing Street in violation of lockdown rules.

• Despite tanking approval ratings, Johnson's allies are pointing to his powerful surprise visit to Kyiv last weekend as a sign that a war — even one in which the U.K. isn't fighting — is no time to replace a prime minister.

Driving the news: Johnson isn't exactly waiting quietly for things to blow over. He unveiled a £120 million plan today to send asylum-seekers who illegally cross the English Channel on a one-way flight to Rwanda, where they'll receive housing paid for by the British government.

• Labour Party leader Keir Starmer blasted the plan as "unworkable" and "extortionate" and an attempt to distract from Johnson's own law-breaking
• Johnson acknowledged that it would likely face legal challenges from "politically motivated lawyers."
• Context: A sharp rise in Channel crossings has become a liability for a prime minister who led the Brexit campaign to "take back control" of Britain's borders. The U.K. has also been stingier than most European countries in accepting Ukrainian refugees.

What's next: Johnson's Teflon reputation will be put to the test on May 5, when the U.K. holds local elections for the first time since the Labour Party took the lead in national polls.

Israeli ambassador to the U.S. Michael Herzog said Thursday that it would be "very important for our region" if the U.S. and Saudi Arabia were to "fix" their relationship.

Why it matters: U.S.-Saudi relations have been rocky since the start of President Biden's term. On the campaign trail, Biden promised to make the kingdom a "pariah," and later he released an intelligence report directly blaming Crown Prince Mohammed bin Salman for the murder of journalist Jamal Khashoggi.

• The Saudis have recently rebuffed U.S. requests to increase their oil output, opting instead to stick to a production pact reached with Russia.
• The Biden administration has been walking a tightrope, engaging with Saudi officials on security and energy issues while keeping the crown prince himself at arm's length.

On the one hand: The Israeli government is concerned that the tensions between the Biden administration and Saudi Arabia will push the Saudis toward Russia and China and lead to less U.S. engagement in the Gulf, which could embolden Iran.

• "Saudi Arabia is a hugely important actor in our part of the world and in the Islamic world as a whole," Herzog said, adding that the Saudis would also be unlikely to recognize Israel before repairing relations with Washington.

On the other hand: 32 House Democrats — including Reps. Gregory Meeks and Adam Schiff, chairs of the Foreign Affairs and Intelligence committees, respectively — wrote to Secretary of State Tony Blinken on Wednesday urging him to "recalibrate" the relationship.

• "Our continued support for the Saudi monarchy, which systematically and ruthlessly represses its own citizens, targets critics all over the world, carries out a brutal war in Yemen, and bolsters authoritarian regimes throughout the Middle East and North Africa, runs counter to U.S. national interests and damages the credibility of the United States to uphold our values," they wrote.

As the war in Ukraine pushes global food and fuel prices to new highs, and the world mobilizes to aid Ukrainian refugees, humanitarian groups warn that the years-long crisis in Yemen stands to get much worse, Axios' Laurin-Whitney Gottbrath reports.

On the ground: "We are doing more with less, and ... we're going in the direction of just having to do less with less," says Yasmin Faruki, a senior policy adviser with Mercy Corps who recently returned from a trip to Yemen.

• Even before the war, humanitarian groups like Mercy Corps had to make tough decisions about their level of aid due to funding shortfalls, rising food prices and growing need.
• Yemenis are now "completely dependent on international assistance," Faruki explains, creating a "multiyear Band-Aid approach in which you can't really have sustainable infrastructure solutions."
• The country relies almost entirely on food imports, with 30% of its wheat coming from Ukraine, per the UN humanitarian office.
• "We have no choice but to take food from the hungry to feed the starving," World Food Program executive director David Beasley said last month, after announcing reductions of food rations to 8 million people.

While a two-month truce brokered by the UN gives cause for cautious optimism, humanitarian groups say the lack of international attention is still dangerous.

• "It's repugnant and unacceptable that we would just kind of turn our backs on people who have been suffering for way too long," Faruki says.
