Russian strategic nuclear weapons might be deployed to Belarus along with part of Russia's tactical nuclear arsenal, Belarusian President Alexander Lukashenko said Friday.

Russian President Vladimir Putin announced last week that his country intended to deploy tactical, comparatively short-range and small-yield nuclear weapons in Belarus.

The strategic nuclear weapons such as missile-borne warheads that Lukashenko mentioned during his state-of-the nation address would pose an even greater threat, if Moscow moves them to the territory of its neighbor and ally.

"We need to work to grow the US presence in our region on the eastern flank in terms of troops and equipment," Romania's Foreign Minister Bogdan Aurescu said after talks with his counterparts in the so-called Bucharest Nine.

Ministers from Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania and Slovakia reiterated calls for boosting the defence capabilities of the region which borders war-torn Ukraine.

"If we have a strong defence, then we are able to project a strong deterrence as far as Russia's destabilizing and assertive conduct is concerned," Aurescu said following the talks in a Polish city of Lodz.

"This is the only language Russia understands," he added.

Aurescu called for "more air defence, more anti missile capacities on our territories... more surveillance, reconnaissance and intelligence means."

The B9 countries also pledged further support for Ukraine in fending off Russia's invasion.

"The B9 countries are leaders here, also in terms of mobilising the allies to bolder actions, as it was in the case of transferring the MiG-29 fighter jets or tanks," Polish Foreign Minister Zbigniew Rau said.

"We all support the accession of Ukraine to NATO," Aurescu added, saying that "the priority now is to support Ukraine to win this war."

Belarus was a staging ground for Russian troops to launch their invasion of Ukraine a little over 13 months ago. Lukashenko, in office since 1994, delivered his annual address amid escalating tensions over the conflict in Ukraine.

Both Lukashenko and Putin have alleged that Western powers want to ruin Russia and Belarus.

“Putin and I will decide and introduce here, if necessary, strategic weapons, and they must understand this, the scoundrels abroad, who today are trying to blow us up from inside and outside," the Belarusian leader said. "We will stop at nothing to protect our countries, our state and their peoples.”

“We will protect our sovereignty and independence by any means necessary, including through the nuclear arsenal,” Lukashenko said . “Don’t say we will just be looking after them, and these are not our weapons. These are our weapons and they will contribute to ensuring sovereignty and independence.”

Belarusian opposition leader Sviatlana Tsikhanouskaya, who was forced to leave Belarus under official pressure after challenging Lukashenko in the 2020 presidential election that the opposition and the West, denounced Lukashenko's push for Russian nuclear weapons as a betrayal of national interests.

“The deployment of nuclear weapons in Belarus put the lives of Belarusians in serious danger and turns our country into a potential target for strikes, including nuclear strikes at the whim of the two dictators,” Tsikhanouskaya told The Associated Press.

Earlier in the address, Lukashenko called for a cease-fire in Ukraine.

A truce must be announced without any preconditions, and all movement of troops and weapons must be halted, he said.

Belarus and Russia have intensified their military cooperation since the start of the Ukraine war. Moscow has kept its troops and weapons in Belarus, although no Belarusian troops have participated in the fighting.

Belarus, Ukraine and Kazakhstan all relinquished Soviet nuclear weapons, which were left on their terrotories after the 1991 collapse of the Soviet Union. Under the so-called Budapest Memorandum that accompanied giving up the weapons, Russia, the United States and Britain agreed to respect the territorial integrity of those countries.

Ukraine has repeatedly complained that Russia's 2014 annexation of Crimea from Ukraine and the 2022 invasion violate that agreement.

Lukashenko said Friday that he did not want to lose his country's nuclear weapons but was pressured into doing so by then-Russian President Boris Yeltsin.

Speaking about the possible deployment of Russian strategic nuclear weapons to Belarus in Friday's speech, Lukashenko said that a week ago he ordered his military to immediately put the former base for Soviet intercontinental ballistic missiles in order to make it ready for use. “It's a highly technologically sophisticated structure,” he said.

“All the infrastructure has been created and is standing ready,” Lukashenko declared. “I'm sure that those measures will help sober up all those hawks across the ocean and their satellites for a long time ahead and force them to reckon with our people if they don't understand different language.”

"The next month, the next period will be crucial for the fate of the war in Ukraine," Aurescu said.
