text:  Live from NPR News, I'm Dale Willman. President Biden and First Lady Jill Biden hosted a 4th of July celebration today for military and veterans families, as well as caregivers. Addressing the crowd, Biden spoke about the strength of the U.S. military. You're incredible. Understand, you are the finest fighting force in the history of the world. That's not hyperbole. In the history of the world, there's never been another military as powerful, as decent, and as giving as our military.
