"His [Biden's] mind was shaped in the cold war logic ... You do not talk about Nato membership for Ukraine with him. Do not talk about nukes to him. Because these are the things that trigger him," Kuleba said in an interview with the Financial Times newspaper published on Friday.
He also believed that Ukraine is lucky that Biden was elected US president in 2022, otherwise the situation for Kiev would have been much worse.
When asked by a journalist about why, in his opinion, Western allies were not in a hurry to supply weapons to Ukraine, Kuleba replied that this was usually the most difficult question.
Last week, The New York Times reported that some US and European officials were allegedly proposing the return of nuclear weapons to Ukraine. Kremlin spokesman Dmitry Peskov said that discussions about the possibility of deploying nuclear weapons in Ukraine are irresponsible, and this is said by those who have a poor understanding of reality.
