Is Donald Trump accelerating the US dollar’s demise as the world reserve currency?

Correct me if I’m wrong, but even before Trump entered the scene, the US dollar was at risk of no longer being the world reserve currency. Now with trump’s impulsive decision making in regard to economics (universal tariffs, Iran war), there appears to be a more accelerated risk of the US dollar’s demise losing its status as the world reserve currency sooner than anticipated. I hear the Chinese Yuan or the Euro would be among the most likely currencies that can replace it.
