I just thought my previous comment did not come out quite right. Big politics and influencing the entire humanity is a complex thing. Because of very long very complicated and wrong history. It is very much an exception where the middle finger and interfering with the matters of others could be the right approach.
In all other cases, especially in anything of a smaller scale, the right approach is to live alone in the woods/oceans - nature, and not engage in anything except when somebody comes to ask for an advice. And even then, put yourelf in the shoes of the requestor, and see what kind of an advice he is capable to interpret right. That is pretty much what Buddha did.
