I suggest ignoring "geopolitics", and considering to what extent your input matters even in local political matters. If you find that such impact is minimal locally, then from a political consideration, it is a waste of your time to spend energy on "Russian threat" or any other geopolitical narrative (many dating to 19th century.) You should focus on your local issues.
Geopolitical policy is opaque to uninitiated and uninformed. It is not clear to me why the elite make a show of discussing geopolitics for the public at large. Join CFR in a meaningful capacity and you may get a whif of what actually are the dynamics and issues that drive international relations.
This is hopelessly naive, imho. The information asymmetry is off the charts, and a rational "analyst/reader" (the role you want to play) of geopolitics should be aware of this fact, and its implications. You simply have no idea what is really going on. You don't have the data and it is naive to assume what is printed in a handful of outlets by an equally limited number of promoted authors are the "geopolitical facts".
So, yes geopolitics certainly "matter" but that was not the point.
However I resent the dumb propaganda that is served to us and has no basis in reality.
