What was the theme of Biden's speech yesterday?

"Division",,, Get one group to "hate" another group,,, blame them for all their problems... Make the group who thinks for themselves the enemy and at fault for everything bad in the world...

What would be the most basic intent of this strategy???
In a military context considering it as a tactic of psychological warfare it would be a progression of the "force continue'm"..

The intent of this psychological tactic is to incite "violence" between distinct groups of people... This is exactly the kind of thing you would do if you wanted to start a "civil war"...

What is the biggest and best kind of distraction you can get if you want the "people" focused on each other and not "you"???
