Russia's former president joked that NATO wouldn't come to the aid of Ukraine if they were hit by Russia.

The leader of Russia's Security Council took aim at US President Joe Biden and the NATO alliance on Telegram early Tuesday.

He accused the leaders of threatening "terrifying consequences" if Russia uses nuclear weapons, and of being ready to start an exchange of nuclear strikes with our country.

Russia can retaliate with nukes or conventional weapons if it is hit with nukes or if it is attacked with conventional weapons.

Russia will do everything in its power to prevent the emergence of nuclear weapons in hostile neighbors such as Ukraine.

He said that the threat to Russia would have to be responded to. Without long consultations. It isn't a bluff.

NATO member states will put their own security ahead of protecting a dying Ukranian if Russia strikes it with a nuclear weapon.

An isolated Russia

Putin using a nuclear weapon would bring him down, according to a security expert.

He argued that NATO would hit back with conventional weapons, despite the whole world turning against him. He predicted that China would stop supporting Russia.

The associate director of the Strategy and Security Institute at the UK's University of Exeter thinks that there will be an immediate increase in the campaign.

Russia is moving to annex large parts of occupiedUkraine through sham referendums.

According to the UK's Ministry of Defence, any attempt to re-take those areas could be seen in Moscow as an attack on Russia.

Putin and his allies have been reminding the world about Russia's nuclear weapons. In February he mentioned it, and in March he said Russia had the right to use nukes.

A recent string of statements like these is trying to ramp up the threat and scare the West away from further support of Ukraine because Putin is in a corner.

Putin's announcement to call up reserve troops has been viewed as a desperate act by the international community.

Turkey, India and China have snubbed Putin.

The man said that Putin was humiliated.

Is Putin bluffing?

The White House warned Russia that it would face catastrophic consequences if it used nuclear weapons.

Zelenskyy said he didn't think Putin was bluffing.

The West must still take Russia's threats seriously, despite the fact that they are a bluff.

He said that even when people are bluffing, they get locked into doing what they thought they wouldn't have to do.

He said that the danger of a mistake or sheer miscalculation can never be ruled out. The West has to pay attention.

The defense minister of Russia's neighbor, Latvia, told Insider that he thinks Putin is bluffing in order to get the West to reduce its support forUkraine.
