It's not that you plan to do nothing; rather, it's because you can do nothing about them. The only people who have any sway are the various foreign offices and the country leaders. But even their power is incredibly limited, because humanity moves like the tide.
Sure, Trump can continue chastising Netanyahu for continuing Israel's attacks into Gaza and Lebanon (which will sabotage the already comical agreement between the USA and Iran), but Netanyahu is in a bind with an October election coming up (and a hardliner rival who's already calling him a 3-failed-war-leader), so he can't change course no matter how much Trump (who needs a Republican victory in November) gets pissed off and threatens him. And even those threats will largely be empty because losing the religious right would be catastrophic. And no one else at either helm could do any better.
And because of that, Iran knows it can just continue like it always has, slowly working towards a bomb, with Saudia Arabia and Turkey soon following suit (they can't allow Iran to be the only nuclear power in the region - not with an isolationist USA).
Then we have Russia, whose insecurity and "defensive expansionism" spans centuries, stemming from its geography, so there's simply no way to placate them, and no way for them to ever be happy about NATO (which everyone already knows is a paper tiger anyway - it's just a matter of sussing out where the real alliance lines lay).
So yeah, you're not going to solve it. I'm not going to solve it. Nobody's gonna solve it. We're just gonna ride the tide.
