Every time Joe Biden speaks, he proves to our adversaries that the United States, the titular head of NATO, is being led by an invalid who should be at home sitting on a shaded deck with a cold glass of tea watching the birds, not in the Oval Office.

And every time he speaks and sounds as though he's halfway to dementia and Alzheimers, he further empowers those enemies to act.

When Donald Trump was president, he made it clear to our allies and enemies alike he was large and in charge and fully in control of his faculties. They knew when he spoke, when he warned, when he threatened, he wasn't bluffing, as he proved on numerous occasions.
