The USA will react harshly to a strike on Ukraine with nuclear weapons.

This will not depend on which nuclear weapon Russia will use against Ukraine. 

This was said by US National Security Adviser Jake Sullivan. 

Sullivan was asked by journalists whether the USA would react if Russia uses tactical nuclear weapons against Ukraine, to which he replied that it does not matter which nuclear weapon is launched against Ukraine - the answer will be harsh. 

"The use of nuclear weapons on the battlefield in Ukraine is the use of nuclear weapons on the battlefield in Ukraine," said Jake Sullivan. 

The US national security adviser added that they are cooperating with countries such as India and China and have sent a very clear warning to Russia about the inadmissibility of using nuclear weapons against Ukraine. 

Threats to Russia with nuclear weapons 

At the end of September, Russian dictator Vladimir Putin attempted to illegally annex four Ukrainian regions.

In his speech, he began to hint at the possibility of using nuclear weapons in the war against Ukraine. 

American philosopher and political scientist Francis Fukuyama said that if the Russian Federation uses nuclear weapons against Ukraine, the US and NATO may go to war.

In his opinion, the United States will introduce a no-fly zone over the entire region and begin to shoot down Russian planes and attack bases from which missiles are launched.

The US could 

sink most of Russia's Black Sea Fleet relatively quickly.

NATO Secretary General Jens Stoltenberg said that if the Russian Federation uses nuclear weapons, these will be "red lines" that will change the nature of the war.
