Why is Putin insulting putin instead of working with him like democrats did with russia before to make peace?

The "insult" is something Putin himself has repeatedly bragged about being.

And "good relations" isn't remotely what we had under Trump.

There was no insult.  Biden was asked a question and he answered honestly.  I thought you guys LOVED when a politician speaks his mind!

Stephanopoulos: "So you know Vladimir Putin. You think he's a killer?"

Biden: "Mmm hmm, I do."

The Democrats are itching for a good World War.

No you mean Biden is a little putin . That's how Trump Wood handle it 

Putin hated Trump. Sure Trump talked nice to Putin but then bombed Putin's allies and sanctioned Putin's government. 

Putin had Trump in his back pocket.

I hear ya bro! Biden should love on him. maybe exchange love letters.

All Biden did is call Putin a killer, which is the truth. If that offends Putin then he's a puzzy too.

I completely agree.  It makes no sense for Putin to insult Putin.
