'We stand with you', Biden tells Ukraine in his Warsaw speech

US President Joe Biden has said in his address on Russia’s invasion of Ukraine delivered to the Polish people outside Warsaw’s historic Royal Castle that his message to the Ukrainian nation is "we stand with you."

Biden made the address on Saturday in the Polish capital, where he earlier met with the Polish president, Andrzej Duda.

"My message to the people of Ukraine is a message I delivered today to Ukraine's foreign minister and defence minister, who I believe are here tonight. We stand with you. Period," Biden said.

"There is simply no justification or provocation for Russia's choice of war. It's an example one of the oldest human impulses using brute force and disinformation. To satisfy a craving for absolute power and control. It is nothing less than a direct challenge to the rule-based international order, established since the end of World War Two," he added.

Biden also said that Russia's invasion of Ukraine threatened to unravel global security, and that the world's democracies must prepare for a long fight against autocracy. He called the fight against Vladimir Putin a "new battle for freedom."

The US president said that Nato is a defensive alliance and it has never sought Russia's demise and added that American forces are in Europe to defend Nato allies, not to engage with Russian Forces.

But he also said that Nato has "a sacred obligation under Article Five to defend each and every inch of Nato territory with a full force force of our collective power."

“Don’t even think about moving one single inch of Nato territory,” he added.

He also said that "swift and punishing costs" are the only things that will get Russia to change its course.

The US president pointed out that the United States has sanctioned 140 Russian oligarchs and their family members "seeking their ill-gotten gains, their yachts, their luxury apartments, their mansions," and "more than 400 Russian government officials including key architects of this war."

"These officials and all the guards have reaped enormous benefit from the corruption connected to the Kremlin. And now they have to share in the pain the private sector is accurate as well," he added.

Biden also said that international sanctions on Russia "are sapping Russian strength, its ability to replace its military, its ability to project power."

"As a result of these unprecedented sanctions, ruble almost is immediately reduced to rubble," he added.

“Russian economy was ranked the 11th biggest economy in the world before this invasion. It will soon not even ranked among the top 20 in the world,” he continued.

"Alongside these economic sanctions, the Western world has come together to provide for the people of Ukraine with incredible levels of military economic humanitarian assistance," Biden added.

He also recalled the words of the late Polish-born Pope John Paul II "Do not be afraid," which he said during his first public address after his election in October 1978.

"There were the words that would come to define Pope John Paul II, words that would change the world. It was a message that helped add the sober repression and the central land in Eastern Europe 30 years ago. It was a message that will overcome the cruelty and brutality of this unjust war, Biden said.
