Russia's War Against Ukraine: Diplomatic

Talks and U.S. Policy



Updated August 7, 2026

The Russian Federation (Russia) launched a full-scale invasion of Ukraine in February 2022. More than
four years later, Russia and Ukraine remain engaged in Europe's largest war since World War II. With
estimates of up to 2 million or more killed or wounded, and with Russia controlling about 20% of
Ukraine's territory, neither side appears poised to achieve a decisive military victory. In 2026, Ukrainian
forces have limited-and in some cases reversed-Russian gains and markedly expanded a campaign of
long-range attacks against Russian oil facilities and logistics infrastructure.
The second Trump Administration has engaged in efforts to facilitate an end to the Russia-Ukraine war.
Formal negotiations were last held in February 2026; whether negotiations will resume-and, if so,

forniat in Abu Dhabi, United Arab Emirates, in January 2026. Two rounds of U.S.-mediated talks
followed, but formal peace talks have not resumed since U.S.-Israeli military operations against Iran
began in late February 2026.
In an August 2025 meeting with President Trump in Anchorage, AK, Russian President Vladimir Putin
reportedly proposed a ceasefire along the line of contact in two of Ukraine's southern regions, if Ukraine
transferred populated areas of its eastern Donetsk region to Russia. This proposal appeared to be included
as an element of subsequent talks, but Ukrainian authorities rejected it, maintaining (among other reasons)
that the transfer of this heavily fortified fortress belt would greatly diminish Ukraine's ability to defend
itself from further Russian aggression.
In May 2026 remarks to the press, Secretary of State Marco Rubio said Russia-Ukraine talks had not been
fruitful and the Trump Administration was not interested in getting involved in an endless cycle of
meetings that lead to nothing. In July 2026, Secretary Rubio referred to the failed efforts that began in
