US President Donald Trump announced a deal with Russian President Vladimir Putin for Moscow to supply millions of tons of diesel fuel to American and global markets. 

The announcement would give Russia a major opportunity to sell fuel abroad at a time when Ukraine is targeting its oil industry to deprive Moscow of revenue and disrupt the resources sustaining its invasion. The US president has increasingly called for Ukraine to halt strikes on Russian oil infrastructure in recent weeks, blaming Ukraine for high fuel prices in the US.

Trump’s push for Kyiv to halt those attacks, alongside his effort to secure Russian fuel supplies, risks undermining Ukraine’s campaign to put economic pressure on the Kremlin while the US seeks to contain the fallout from its war with Iran.

Trump promises millions of tons of diesel from Russia

In a 9 October post on Truth Social, Trump said Russia would immediately supply more than 300,000 tons of diesel, followed by another 500,000 tons in November and 1 million tons shortly afterward. He also announced a possible additional delivery of 3 million tons, conditional on the state of Russian refineries.

“Diesel Prices for Americans and, indeed, the World, will be COMING DOWN, IN RECORD NUMBERS, AND FAST!” Trump wrote, describing lower fuel prices as a top priority for American farmers, ranchers, and truckers.

Trump's announcement did not explain how the promised volumes would be reconciled with the condition of Russian refineries amid ongoing Ukrainian strikes, which he cited as a factor determining the timing of later deliveries.

Trump has pressed Ukraine to stop targeting Russian refineries

The announcement comes after Trump repeatedly blamed Ukrainian strikes on Russian oil infrastructure for worsening global diesel shortages and driving up fuel prices.

Ukraine has continued targeting Russian oil facilities as part of its campaign to undermine Moscow's war economy. Ukrainian strikes have damaged refining capacity, contributed to fuel shortages inside Russia, and forced Moscow to restrict fuel exports. 

Kyiv has argued that the attacks put pressure on Russia's ability to finance and sustain its war against Ukraine.

Iran war drives fuel prices higher, not Ukraine

The rise in US fuel prices stems largely from the US-Israeli war with Iran and its disruption of global energy supplies, according to Reuters. The conflict has disrupted shipping through the Strait of Hormuz, a strategic waterway through which roughly one-fifth of the world's oil supplies normally pass, pushing energy prices higher. 

Trump has nevertheless blamed Ukraine's refinery strikes for rising fuel costs while pressing Kyiv to halt them.

Ukraine's attacks on Russian oil infrastructure are intended to weaken Moscow's war economy. By contrast, the disruption to global energy shipments stems largely from the conflict with Iran. 

Zelenskyy warns Russian diesel deal would fund further attacks on Ukraine

Ukrainian President Volodymyr Zelenskyy warned later on 9 October that allowing Russia to sell petroleum products abroad without securing a lasting de-escalation agreement would help finance Moscow's war against Ukraine.

“Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged,” Zelenskyy said, responding to Trump's announcement of a proposed Russian diesel supply deal.

Zelenskyy said Ukraine's strikes on Russian oil refineries and other oil facilities were a response to Russia's years-long campaign against Ukrainian energy infrastructure. He offered a reciprocal arrangement under which Ukraine would stop striking Russian refineries if Russia stopped destroying Ukrainian energy facilities, saying the United States had sufficient leverage to secure such an agreement.

“Ukraine will not burn Russian oil refining facilities if Russia does not destroy our energy infrastructure,” Zelenskyy said.

He also urged Washington to maintain pressure on Moscow, including sanctions under the proposed Graham legislation, and to continue supporting Ukraine's defense. Zelenskyy argued that easing sanctions without a clear, sustained de-escalation agreement would signal weakness and give Russia more time and resources to continue the war.

“Gifts to Putin will not bring peace,” Zelenskyy said, warning that Russia would respond to diesel supplies with further terror and attacks. He called on the United States to pursue a reciprocal de-escalation agreement and press Russia to stop its attacks on Ukrainian energy infrastructure.

Two Ukrainian defense-tech firms, The Fourth Law and Odd Systems, have joined forces to mass-produce thermal imaging sensors in Europe and the US, The Fourth Law told Militarnyi. The goal is to wean Western militaries off foreign suppliers, chiefly China, for the core part of every thermal camera.

Amid Russia's daily attacks, Ukrainian drone makers have been shifting production to allied countries. Linza and Zoom drones are now built in Germany, and another top manufacturer has taken its technology to Canada and Finland. Sensor plants would move a core component west, not just finished drones.

A Western answer to Chinese sensors

The project, called Project Foundation, will build long-wave infrared sensors, known as microbolometers. These chips register heat, so a camera can pick out a person or vehicle at night or through smoke. The aim, The Fourth Law said, is to "ensure the sovereignty of Western countries in the field of thermal imaging technology."

Plants in Europe and the US from 2027

The project will run two sites, First Foundation in Europe and Second Foundation in the US, from a headquarters in Eindhoven, a Dutch semiconductor hub. Mass production is due to start in 2027. Within three years, the partners want to quadruple Europe's output of these sensors and double America's.

Why Europe's supply isn't enough

Ukraine's front line burns through sensors faster than Europe can make them. "Europe currently produces less than 500,000 such sensors per year, while Ukraine consumes this amount in about five months," Odd Systems co-founder Yaroslav Azhniuk said in February, when he first announced plans for a plant able to make one million sensors a year. European sensors cost about five times as much as Chinese ones and are hard to buy at all, because Europeans need them too, he added.

Factories working for Ukraine abroad have already become sabotage targets. In March, an arson attack in Pardubice, Czechia, destroyed nearly all the production capacity of a plant making drones and thermal sights for Ukraine's army. Czech investigators are looking into a possible Russian trail behind the attack.
