As the US presses for an end to Russia’s war on Ukraine, the fate of territory in the Donbas and a massive nuclear power plant may be the biggest barriers to a peace deal. Here’s a look at these and other obstacles, including the mechanics of security guarantees and a potential vote in Ukraine.

Ukrainian President Volodymyr Zelensky said Wednesday his country was "10 percent" away from a deal to end the war with Russia, but cautioned that the most important issues were unresolved and warned against rewarding Moscow.

Ukrainian President Volodymyr Zelenskys remarks came shortly after Russian President Vladimir Putin reiterated his belief that Moscow would prevail in the ongoing conflict.

Speaking at a joint press conference, both US President Donald Trump and Ukrainian President Volodymyr Zelensky were cautiously optimistic about negotiations over the 20-point peace plan for Ukraine. But progress made doesn't include issues of security guarantees for Ukraine, nor the country's eastern Donbas region. So what is blocking the negotiations?

US President Donald Trump hosted Ukrainian President Volodymyr Zelensky in Florida to discuss a draft peace framework aimed at ending Russia’s war. Ukraine is seeking long-term US security guarantees, with Zelensky saying he has asked Trump for commitments lasting up to 50 years, beyond the 15 years currently envisaged.
