Recruiting has been a challenge for decades, and virtually all other volunteer militaries in developed countries are facing the same issues despite having very different cultural backgrounds and norms. So that's unlikely to be the cause.
Maybe the incentives don't align with possibly being forced to die in the front lines of world war three? Military recruits tend to be younger folks, and if you haven't noticed they aren't particularly enamored with the state as it stands today.
There are innumerable factors that go into people deciding to join the military. What makes you think “wokeness” is the reason for declining recruitments? Why not stronger labor markets or the end of major wars in Iraq and Afghanistan?
