Former President Joe Biden accuses the Trump administration of "modern app mouth" while dealing with Russia's Vladimir Putin and risking the transatlantic alliance The world war has been around for 80 years.

In his first interview since leaving the office in January, Biden told BBC Radio 4's "Today" plan that it was "stupid" that Putin would permanently acquire the territory seized by troops after the 2022 invasion, which President Donald Trump and senior officials said could be necessary to obtain a peace deal.

In extensive interviews Wednesday morning, Biden also provided a passionate defense of his economic record and U.S. aid to Ukraine, while sending a strong wording attack on the incumbent administration.

Sometimes Biden sounded hoarse, once apologizing for the ongoing cough, and at other times he seemed verbally shocked, a reminder of a disastrous presidential debate with Trump, which ended his reelection campaign last July.

"I just don't understand how people think that if we allow the dictator, a thug decides that he will take not very well with most of his land, that will satisfy him," Biden said. ”

"This is modern comfort," he said, referring to the fact that in the 1930s, when Britain and other countries' policies towards Nazi Germany, leaders hoped that war would be avoided if Adolf Hitler was allowed to obtain a series of territorial gains.

Biden said: "What this guy wants to do is re-establish the Warsaw Convention - he can't stand the fact that the Russian dictatorship he runs and the Soviet Union collapsed.

Biden spoke in honor of the 80th anniversary of VE Day, which marked the Allied victory in Europe at the end of World War II and believed that NATO has successfully secured Europe and the wider world since then.

Trump criticizes Nato favors the isolationist "America First" foreign policy and says that there have been significant changes in the U.S. policy toward the alliance, including ending U.S. command on NATO's actions in Europe.

When asked if the league could go away, he said: “It’s a serious problem and I think if that happens, it will change the modern history of the world.

"We are the only country with the ability to bring people together and lead the world. Otherwise, you will have China and the former Soviet Union, Russia, step up."

He added that the threat to democracy is now more severe than at any time since World War II, without NATO's buffer - all members must defend any member under attack in military terms and under Article 5 of the Treaty, Putin will not stop in Ukraine.

"Look at the number of European leaders and wondering, 'What should I do now? What is the best way I can go? Can I rely on the United States, will they be there?' They are not expanding democracy around the world, they are retreating," he said.

Biden said Trump and Ukrainian President Volodymyr Zelenskyy's extraordinary argument in February were "under the United States" and said it was part of a broader trend that the Trump administration has broken with long-standing traditions and norms.

"Their way we talk about the U.S. Gulf, or we need to take Panama back, maybe we need to buy Greenland, maybe Canada. What's going on here? Biden said.

When asked if Trump's behavior is more like a king than a president, Biden said: "I would rather not comment. He does not behave like a Republican president."

Some critics argue that Biden is reluctant to arm Ukraine, especially long-range missiles in the early stages of the Russian invasion, meaning Keeff failed to defeat Putin's troops on the battlefield.

Trump also accused Biden of the war for Ukraine, which began with a full-scale invasion of its smaller neighbors by Russia and said it would not have happened if he was president.

Biden argued in an interview that his administration managed to avoid a world war between nuclear powers and “give them everything they need to be independent” and that he would respond more positively if Putin actually moved again. ”

Regarding whether he correctly left the Democratic nomination and endorsed Kamala Harris, or whether he should listen to critics and do it faster - Biden admits it was a tough choice.

"Things move so fast that it's hard to get away. It's a tough decision," he said. "I think it's the right decision. I think … it's just a tough decision."
