Please explain why the Dollar is still so strong despite everything happening?

Usually, when a country's lead is communicating clear emotional instability, that has an immediate impact on the trust into the country's economy.

Why is the dollar so strong right now? It was 15% weaker 5 months ago.

What happens?

The course just jumped from 1.16 to 1.15 USD/EUR, but why? Where does the strong signal come from?
