The United States has given Ukraine a “take it or leave it” ultimatum, warning that an offer of NATO-style security guarantees could be withdrawn if Kiev does not agree to Washington’s proposed peace terms, according to The Telegraph.

European and UK leaders have called for the deployment of a European-led military force to Ukraine in the event of a ceasefire with Russia, along with US-led “monitoring” teams and the “regeneration” of Kiev’s own army.

The United States, Ukraine and major European countries have reached consensus on 90 percent of terms for an accord to end Ukraine’s war, two senior American officials said Monday, but they say questions of territorial control have yet to be resolved.

During negotiations in Berlin, the Kiev authorities allegedly agreed to hold elections within 100 days and to refrain from seeking NATO membership under certain conditions, Bild has reported.

The delegations of the United States and Ukraine achieved “a lot of progress” during negotiations in the German capital of Berlin, American Special Presidential Envoy Steve Witkoff has stated.

Ukraine has relinquished its ambition of joining the NATO military alliance in exchange for Western security guarantees as a compromise to end the war with Russia, President Volodymyr Zelensky has stated ahead of talks with U.S. envoys in Berlin.

Russia’s oil and gas revenue in December is expected to be nearly half compared to the previous year, Reuters has reported.
