Washington, Aug 12: The meeting in the Oval Office between U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy was a diplomatic car crash.

“Your country is in big trouble. You’re not winning,” Trump said, dressing down Zelenskyy in front of the world’s media. “You don’t have the cards.”

The blowup in February 2025, three years into the war, was more than just a heated public exchange: The Ukrainian delegation was asked to leave the White House, and Washington briefly suspended intelligence sharing with Kyiv. In the ensuing months, as Russia made slow but steady gains on the battlefield, Trump warmly welcomed Russian President Vladimir Putin in Alaska and seemed ready to push Ukraine into an unfavorable peace deal, including forcing it to give up territory.

But even as Zelenskyy sat next to Trump, his forces were preparing an operation that would reveal Ukraine’s ability and ambition to take the war to Russia: Months later, drones smuggled into the country attacked Russian bombers, destroying or damaging planes worth hundreds of millions of dollars.

Since then, Kyiv has ramped up a campaign of longer-range strikes inside Russia and in areas Moscow has seized, increased production of weapons, targeted Russian air defenses, and hit oil infrastructure and the warehouses of a major retailer in a bid to ensure ordinary Russians feel the impact of the conflict.

In an embarrassment to Putin, Ukrainian drone strikes sent thick plumes of smoke billowing over St. Petersburg shortly before the opening of an international economic forum in June. Concern over Ukraine’s attacks led Russian authorities to scale down the May 9 military parade commemorating the defeat of Nazi Germany. Strikes on oil refineries have caused a summer fuel crisis.

By the time Trump and Zelenskyy met at a NATO summit in July, the American president said the Ukrainian leader had “been very effective” in the war. “We’ve actually developed a good relationship,” Trump added.

But as Ukraine’s strikes have intensified, so have Russia’s — and Kyiv faces major challenges in defending against them because of shortages of American Patriot air defense missiles.

In the first six months of the year, 1,396 civilians were killed in Ukraine, according to the UN Meanwhile, the world body said Russian authorities reported 250 civilians killed in the same period. On Monday, a strike that Ukraine said hit an oil refinery in Russia killed 13 people, according to local officials.

And while Ukraine’s effort appears to have shifted the narrative about the war in Washington, it’s still not clear if it will be able to push Putin toward the negotiating table.

Ukraine’s strikes are aimed at undermining the idea that Russia can afford to “just let this roll,” said Jack Watling, a senior research fellow at the London-based RUSI think tank.

The question of whether it will succeed depends on how much pain Ukraine can exact. “Logically, above a certain threshold, it does work but whether they can reach that threshold is an interesting question” — and one that depends at least partly on factors outside Kyiv’s control, like continued European financial support, he noted.

Ukraine brings the war to Russia

While most of Ukraine’s strikes have a range of less than 200 kilometers (125 miles), its longer-range attacks have increased dramatically this year. It launched three times as many of those strikes in July as it did in January, according to data from ACLED, an independent conflict monitor. Repeatedly hitting deep into Russia has forced its military to stretch air defenses over a larger area.

Many of its strikes have focused on four key categories of targets, according to an Associated Press analysis of hundreds of Ukrainian attacks this year — compiled from statements by Russian officials and state media and the Ukrainian military.

As the Iran war pushed up energy prices, leading the U.S. to ease sanctions on Russian oil, Kyiv ramped up strikes on oil infrastructure to deny the Kremlin revenue from fuel exports and force shortages on ordinary Russians. It is also striking defense manufacturing to damage Russia’s long-term ability to produce weapons, targeting air defenses to clear a path for its own arms, and hitting retail warehouses to bring the effects to ordinary Russians.

— As part of the campaign against oil infrastructure, Kyiv said it hit Russia’s largest oil refinery, more than 2,500 kilometers (1,550 miles) from Ukraine.

— Kyiv has also targeted defense manufacturing centers. It hit a factory making navigation systems multiple times, including with its own Flamingo missile.

— In July and August, Ukraine struck Wildberries warehouses. Kyiv said the company helps supply the Russian military. Moscow denies that.

— Many of Ukraine’s strikes on Russian air defenses and radar are around Russian-held Crimea and are often carried out with drones.

Maj. Robert “Magyar” Brovdi, the commander leading Ukraine’s drone war, told the AP its strikes in Crimea are also aimed at rendering the peninsula unusable as a staging ground for Russian forces.

Starlink gives Ukraine an advantage — for now

It’s not always clear if Ukraine’s attacks are effective — and some may have resulted in minimal or no damage. In May and June, Ukraine said it hit several satellite, reconnaissance or signals intelligence facilities in Russia, but satellite images analyzed by AP did not show major damage.

Still, Ukraine has one advantage that can help it strip back Russian air defenses and make its drone strikes more precise.

It has access to Elon Musk’s satellite communications service Starlink — which means its operators can control drones in real time in Russian-held Ukrainian territory. Russia has been blocked from using Starlink.

But Russia is also building its own version of Starlink, and is installing jamming systems that hamper Starlink connectivity, Brovdi said.

Ukraine is investing heavily in weapons production

Even before the Oval Office meeting, Ukraine scrambled to invest in new weapons — but that moment was “a real wake-up call,” said a European military official who spoke on condition of anonymity to discuss the front-line situation in detail. It became clear that U.S. support could be stopped “from one day to the next.”

Ukraine doubled down on production, churning out a growing array of weapons in larger numbers and shortening traditional research and production cycles from decades to years or even months.

Even so, Ukraine is still not able to produce as many missiles as it needs. It also took Ukraine time to make systems that could target facilities precisely enough that Kyiv felt comfortable using them to strike deep into Russia, Watling said.

And while Ukraine has begun to resolve navigational issues with its missiles, such as the Flamingo, those weapons are still not as accurate — or as stealthy — as their Western analogues. That often means hundreds of drones must be fired to overwhelm Russian air defenses to allow a missile to get through.

It’s an expensive and time-consuming way to wage war since only 5% to 9% of what Ukraine fires gets past Russian air defenses, according to Watling.

But, although Russia’s weapons are more powerful, Zelenskyy suggested at the NATO summit that Putin is “losing the initiative” in the war as Ukraine has moved the fight from the stalled battlefield to the sky.

Sitting next to Trump at the summit, the Ukrainian leader even cracked a joke, demurring when Trump asked him if he would accept Moscow as a venue for peace talks, as Putin has suggested.

“There are a lot of Ukrainian drones in the air,” Zelenskyy said. “It would be dangerous.”
