What are you considering "high energy physics"? "1/3-1/2 of Nobel Prizes in the 20th century" is a significant overestimation unless you are including topics not traditionally included in high energy physics. For example, there were many Nobel prizes in nuclear physics, which shares various parallels with high energy physics in terms of historical origins, experimental techniques, and theoretical foundations. But nuclear physics is in a very exciting era of experimental and theoretical developments, so your "not looking so good" description does not apply.

Much of nuclear physics was effectively “high energy physics” (or more appropriately named elementary particle physics) back in the day. They ceased to be elementary or high energy at some point. My very loose categorization is everything on the microscopic path towards the fundamental theories; and there’s another macroscopic path, cosmology.

Edit: Expanded a few times.

Agreed on that. My disagreement is with the statement that everything that was once referred to as high energy physics is "not looking so good". Nuclear physics in particular does not feel stuck in the way I've heard some high energy physicists talk about their field.
