With the reelection of Donald Trump, Ukraine may soon have to adjust to a dramatic reduction in US support that could have a decisive impact on the war with Russia, CNN reports.

Throughout his campaign, the Republican president-elect and his running mate, JD Vance, have cast strong doubts on continued US commitment to Kyiv as the war drags on more than two and half years after Russian forces invaded. Moreover, Trump has made comments that suggest the US could pressure Ukraine into an uneasy truce with Russia.

Trump’s victory comes at a precarious moment in the conflict for Kyiv. Russia has steadily been making gains in the eastern Donbas region, which Russia’s President Vladimir Putin aims to capture in full.

Ukraine’s Commander-in-Chief Oleksandr Syrskyi said the situation on the front line “remains difficult” and certain areas “require constant renewal of resources of Ukrainian units” in a statement on Telegram Saturday morning.
