“The worst-case scenario would be to turn the conflict in Ukraine into the start of another global crusade,” Lieven said.

According to him, large-scale financial assistance and arms supplies to Kyiv from Washington exacerbate the situation.

“As the fighting continues, Washington’s involvement in Ukraine’s war effort … has the potential to escalate into a large-scale and direct conflict between two great powers,” Lieven expressed concern.

The official representative of the Russian Foreign Ministry, Maria Zakharova, on the air of the Italian TV channel La7, previously reported that the collective West, led by the United States, had long moved to break off relations with Russia.

At the same time, US Ambassador to Russia John Sullivan stated that it was impossible to completely break off relations between Moscow and Washington.
