The steel mill in a partially occupied region of Ukraine is a dystopian maze of flames, chutes and tentacled pipes, vast enough to be a small city. Thunderous blazes of sparks flash above the open furnaces where workers smelt iron ore into streams of molten metal day and night.

The Zaporizhstal Iron and Steelworks, one of Ukraine’s largest steel plants, lies in the country’s industrial east, where Russia’s 3-year invasion of its neighbor threatens to throttle production at any moment. Daily battles unfold along a front line 40 kilometers (25 miles) away as the plant churns out materials for military equipment and for foreign manufacturers to use in cars, appliances, and construction.

“Morale is not as high as it was before. We are pretty tired here,” plant supervisor Serhii Zhyvotchenko said, reflecting on the hardships. “But there is no way to go back; the only way is forward.”

Last week, though, a second war came to the doorstep of the hulking factory complex: the possible trade war that U.S. President Donald Trump has provoked since returning to office four weeks ago. Trump imposed tariffs of at least 25% on all imported steel and aluminum, a decision that could hurt an essential sector of Ukraine’s battered economy.

The tariff order was not the only action by the president or his administration to cause alarm in Kyiv last week. Trump signaled changing winds in U.S. policy by having a direct call with Russian President Vladimir Putin, whom former President Joe Biden and other Western leaders had tried to isolate since Putin sent troops into Ukraine.

Trump also said that he would “probably” meet in person with the Russian leader in the near future, heightening concerns that Kyiv would be left out of or undermined in any ceasefire talks. Comments by both the president and U.S. Defense Secretary Pete Hegseth rejecting NATO membership for Ukraine further reinforced the fear that the country no longer had Washington in its corner.
