WASHINGTON: US President Joe Biden refused Monday to retreat on the weekend declaration in a major speech that Russian leader Vladimir Putin “could not remain in power” – on the grounds that he voiced “anger.”

didn’t walk back … I wanted to explain it, I wasn’t so, I also now, articulated policy changes. I expressed the moral anger I felt – I didn’t apologize for me personal feelings,” he told reporters at the White House.

Biden’s comments – delivered in Warsaw at the close of the three-day marathon diplomacy on Saturday  seen as a gaffe by the Republican Party and some independent analysts related to a president who went with a combustible conflict.

Biden said he was not worried that it would cover tension with Putin on Moscow’s invasion to Ukraine, adding that he “talked to Russians, telling them what we think.”

I don’t care what he thinks,” Biden added. “This is the man who goes to his own curve and the idea that he will do something outrageous because I call him for what he is and what he does, I think it’s not rational.”

The Ukrainian government said that as many as 10,000 people had died from the beginning of Putin’s invasion more than a month ago.
