Why would anyone in Libland be interested in the motives of its neighbour? Foreign policy and intelligence is normally the realm of a government. Who performs that role in Libland, and what is their incentive to do so?
Perhaps you ought to go to Wikipedia and look up the difference between Libertarianism and Anarchy?
How does a Libertarian system decide which roles (like researching the intentions of foreign states, and defending against them) a government should play, and which (like presumably researching the weather, and defending against natural disasters) it shouldn't?
