One of President Vladimir Putin's closest allies said on Tuesday that Moscow was now fighting the US-led NATO military alliance in Ukraine and that the West was trying to wipe Russia from the political map of the world.

Putin casts the war in Ukraine as an existential battle with an aggressive and arrogant West and has said that Russia will use all available means to protect itself and its people against any aggressor.

Russian Security Council Secretary Nikolai Patrushev is seen by diplomats as one of the major hardline influences on Putin, who has promised victory in Ukraine despite a series of battlefield setbacks.

"The events in Ukraine are not a clash between Moscow and Kyiv - this is a military confrontation between Russia and NATO, and above all the United States and Britain," Patrushev told the Argumenti I Fakti newspaper in an interview.

"The Westerners' plans are to continue to pull Russia apart, and eventually just erase it from the political map of the world," Patrushev said.

The United States has denied Russian claims that it wants to destroy Russia, the world's biggest producer of natural resources, while President Joe Biden has cautioned that a conflict between Russia and NATO could trigger World War Three.

Russia's Feb. 24 invasion of Ukraine has triggered one of the deadliest European conflicts since World War Two and the biggest confrontation between Moscow and the West since the 1962 Cuban Missile Crisis, when the Soviet Union and United States came closest to intentional nuclear war.

The United States and its Western allies have condemned Russia's invasion of Ukraine as an imperial land grab, while Ukraine has vowed to fight until the last Russian soldier is ejected from its territory.

RUSSIA ALONE

As a former Soviet spy who has known Putin since the 1970s, Patrushev's views give an insight into thinking at the very highest levels of the Kremlin. He rebuffed CIA Director William Burns' warnings in 2021 against an invasion of Ukraine.

In a Soviet-style analysis of the West, Patrushev cast Western political elites as corrupt and controlled by trans-national corporations and business clans which planned and executed "colour revolutions" across the world.

"The American state is just a shell for a conglomerate of huge corporations that rule the country and try to dominate the world," Patrushev said.

The United States, Patrushev said, had sown chaos in Afghanistan, Vietnam and the Middle East, and had been trying for years to undermine Russia's "unique" culture and language.

Russia, he said, was a victim of Western designs to push it back to the borders of 15th-century Muscovy, and accused the West of bleeding Ukraine to undermine Russia.

"There is no place for our country in the West," he said.

In response, he said, Russia would achieve economic sovereignty and financial independence but also build armed forces and special services capable of deterring any potential aggressor.

Russian business and private capital, he said, needed to be more "nationally oriented".

"The younger generation should be inspired by the ideas of creative work for the benefit of our Motherland, and not sit in the offices of Western corporations," he said.
