I think you're confusing fear/respect with likability.
I'm sure Joe is a nice, amicable guy and that's why global leaders like him. But, they don't respect or fear him like they did Trump.
That's been proven with the number of global conflicts that have take place under Biden's watch. Like O'bama, his "line in the sand" is always movable. Trump's wasn't.
If Trump were POTUS, he'd give Hamas 24 hours to release all hostages, and if one American hostage were harmed, he'd turn the Gaza strip into a parking lot. And...Hamas would comply.
