Video of Trump's Warsaw speech, noted as being one of the most significant speech since FDR. Take 37 minutes and listen to one of the most important policy statements in American history.

Contrast this with Obama's speeches:  Trump is not "professorial" (read "arrogant"),  gets three times as much said in 36 minutes as Obama could in an hour and 36 minutes, and never refers to himself apart from the context of "what we are doing and have done."
