President Donald Trump is evaluating how far to go to bat for Ukraine. The debate over sending Tomahawk cruise missiles and additional Patriot batteries has sharpened as Russia pounds Ukrainian cities day and night, and as casualty figures climb amid thinning air defenses.Trump campaigned on a promise to end American spending on Ukraine, and he has largely kept it, channeling support instead through European allies who purchase U.S. weapons and pass them on. Still, he has also clearly warmed up to President Volodymyr Zelensky. At the same time, Kyiv has grown more successful on the battlefield. Trump should thus move to increase support for Ukraine. Doing so would be the joint moral, pragmatic, and strategic decision.We should not forget that it was Trump, in his first term, who approved the transfer of anti-tank missiles to Ukraine. That was before the war, but after the Russian occupation of Crimea in 2014. In contrast, the Obama administration had spent two years dithering over whether to send lethal aid. The weapons Trump delivered proved crucial in the war’s opening days, when Ukrainian units shredded the Russian armored columns rolling toward Kyiv. Extending more help now would continue Trump’s initial policy rather than reverse it.
