Iran war deflects attention from Ukraine as an emboldened Russia starts spring offensive

Ukraine's fate is still Europe's top foreign policy issue, fueled by fears that Moscow has wider ambitions. Meanwhile, the Trump administration has wound down talks with Russian and Ukrainian delegations as the Iran war grips its attention. The administration has warned it could turn its back on the conflict if peace efforts come to nothing.

Russian takes in billions after U.S. eases oil sanctions

Only weeks ago, the Russian economy was starting to feel the pinch of sanctions. But Russia is now raking in billions of dollars from a temporary U.S. waiver on oil sanctions against Moscow. The measure taken earlier this month aims to free up Russian oil cargo stranded at sea and ease supply shortages caused by the Middle East conflict.

Ukrainian President Volodymyr Zelenskyy said the U.S. move was " not the right decision " because it will further enable Russia's military campaign.

American Patriot air-defense missiles have been moved from Europe toward the Middle East as Washington redirects resources to its war on Iran. Zelenskyy warned that Kyiv will "definitely" face shortages of Patriot systems because of the war against Iran.

The U.S. produces 60 to 65 missiles per month, or about 700 to 800 missiles per year, Zelenskyy said. "And on the first day in the Middle East war, 803 missiles were used," he said.

Aiming to secure some geopolitical leverage, Ukraine offered its battle-tested technology to help Gulf states fend off Iranian drones. In return, Ukraine wants more of the high-end air-defense missiles that Gulf countries possess and which Kyiv needs to stop Russia's missiles. Zelenskyy also made Ukrainian drone interceptors available to the U.S.

Ukraine desperately needs money, too. A promised 90-billion-euro ($104-billion) loan from the European Union to fund Ukraine's armed forces and its war-shattered economy for the next two years is being held up by Hungary.

Fighting on the front line escalates as weather improves

After a winter of relative calm on the front line, Russia is gearing up for the summer fighting season as fields dry out.

Russian forces are in an early phase of a spring offensive, assaulting Ukraine's eastern so-called Fortress Belt of cities, said Elina Beketova of the Center for European Policy Analysis, a Washington-based think tank.

"Over the past weeks, the Russians have intensified pressure on the battlefield and in the air," she told The Associated Press. In Ukraine's eastern Donbas region, Ukraine's industrial heartland long coveted by Russian President Vladimir Putin, the situation is "critical," she said, though Ukrainian troops say they are holding firm.

"Russia is trying, on the tactical level, some new approaches" with mechanized infantry and armor in its offensive, according to Robert Murrett, a retired vice admiral in the U.S. Navy who is deputy director of Syracuse University's Institute for Security Policy and Law.

Fierce fighting is taking place along the roughly 1,250-kilometer (750-mile) front line snaking along eastern and southern parts of Ukraine, the commander-in-chief of Ukraine's armed forces, Gen. Oleksandr Syrskyi, said this week.

Moscow's forces have made only incremental gains across rural areas. Russia occupies about 20% of Ukraine. That includes the Crimean Peninsula, which Russia seized in 2014.

Russian war bloggers expect a new Moscow effort to create more footholds in the southern Zaporizhzhia and Dnipropetrovsk regions. That would pave the way for a possible push toward those regions' capital cities, which are key industrial hubs.

The Russian tactic is to surround and then choke cities while bombing them to rubble.

Russia bombards civilian areas, Ukraine targets Moscow's war machine

After crushing Ukraine's power grid during one of the worst winters in recent memory, Russian drone and missile barrages of civilian areas have continued unabated.

More than 15,000 Ukrainian civilians have been killed in the war, according to the U.N. Human Rights Monitoring Mission in Ukraine.

For its part, Ukraine has developed long-range drones and missiles to hit targets in rear areas that keep Moscow's war machine going. The targets have included oil refineries, chemical plants, ammunition depots and military logistics hubs up to 1,500 kilometers (900 miles) from Ukraine.

US-led talks are on ice and making little progress

Washington's peace efforts are largely on hold while the White House is "totally distracted by Iran," Murrett said.

Months of U.S.-mediated talks between delegations from Moscow and Kyiv have produced no breakthrough on the knottiest problems, such as who keeps Ukrainian territory and how to prevent future Russian invasions.

Russia has rejected Ukraine's offer of a ceasefire. European leaders have accused Putin of stalling in peace efforts while his army tries to capture more Ukrainian land.

The Kremlin has "never come off (its) maximalist demands" for a settlement, and it would take "overwhelming" Western military and financial support for Ukraine for Putin to back down, Murrett said.
