Burns is the same guy who wrote the famous Nyet Means Nyet memo warning that expanding NATO to Ukraine would provoke war with Russia.

Burns, now CIA Director, was US Ambassador to Russia in 2008, and author of a memo entitled “Nyet means Nyet.” In that memo, Burns explained to Secretary of State Condoleezza Rice that the entire Russian political class, not just Putin, was dead-set against NATO enlargement. We know about the memo only because it was leaked. Otherwise, we’d be in the dark about it.

Even Zelensky’s team knew that the quest for NATO enlargement meant imminent war with Russia. Oleksiy Arestovych, former Advisor to the Office of the President of Ukraine under Zelensky, declared that “with a 99.9% probability, our price for joining NATO is a big war with Russia.”
Arestovych claimed that even without NATO enlargement, Russia would eventually try to take Ukraine, just many years later. Yet history belies that. Russia respected Finland’s and Austria’s neutrality for decades, with no dire threats, much less invasions. Moreover, from Ukraine’s independence in 1991 until the U.S.-backed overthrow of Ukraine’s elected government in 2014, Russia didn’t show any interest in taking Ukrainian territory. It was only when the U.S. installed a staunchly anti-Russian, pro-NATO regime in February 2014 that Russia took back Crimea, concerned that its Black Sea naval base in Crimea (since 1783) would fall into NATO’s hands.
Even then, Russia didn’t demand other territory from Ukraine, only fulfillment of the U.N.-backed Minsk II Agreement, which called for autonomy of the ethnic-Russian Donbas, not a Russian claim on the territory. Yet instead of diplomacy, the U.S. armed, trained, and helped to organize a huge Ukrainian army to make NATO enlargement a fait accompli.
