Hitler left the stadium before the medals were awarded. The 100 meter race was the first of Owens' four medals. It shocked Hitler: his Aryan supremacy myth was in tatters. The only thing worse that could have happened was a Jew winning that first race. He likely didn't want to shake Owens' hand.
Actually Owens was not scheduled to race in the 400 meter relay. It came about only because the American Olympic Committee didn't want to cause an international uproar by allowing 2 Jews to run in the 400. So they replaced both with Owens and Metcalf (who took home a slug of metals himself).
I'm not sure if it is still on Netflix, but a docudrama of the event was made called RACE.

the offensive was shortly won back. But the ability of the Communists
to launch such a widespread coordinated offensive convinced the American
media and ultimately the American public that the war was now a lost
cause and demanded a withdrawal. So, tactically, it was a military
success for the U.S. but it served as a public relations success for
North Vietnam.
I believe the answer may be </span>
<span>U.S. forces dealt the Vietcong a massive military loss and regained control of all areas that the Vietcong had attacked.</span>
