Since the United States decided to go all-in with a focus on the great power competitions

Hello,

Here is the link at the paper that I'm currently reading about new technologies that can trigger uprisings:

New Technologies Could Spark Global Uprisings

When the divide between the (relatively few) “haves” and the (relatively many) “have nots” is in a perpetual state of growth, a breaking point is inevitably reached.

Please, clarify the meaning of "all-in" in the sentence below:

"Since the United States decided to go all-in with a focus on the great power competitions, terms such as irregular warfare, counterinsurgency, and small wars have lost vogue".

go all-in - make a total commitment

 

[milan2003_07]

go all-in - make a total commitment

So, the meaning of the original sentence is that the US decided to make a total commitment (to dedicate themselves to) to focusing on great power competitions?
Does 'great power competitions' mean that sort of a race to reveal one's military and power capabilities (in that case those of the US)?

The competition requires that you are more powerful than your rivals.
