Successive Peruvian and Bolivian lawsuits against Chile create a power conflict. Therefore, legal aspects are only a part of a wider and comprehensive strategy, although in Chile has not been understood on that manner. It is argued that consider international treaties like sacred and intangible, as Chilean diplomacy does, it is more an idealist concept than a realist one. The reality shows that Bolivia and Peru have had the will of “making them tangible”. This situation forces to confront a political and diplomatist’s challenge, considering negotiation.Las demandas sucesivas contra Chile de Perú y Bolivia configuran un conflicto de poder. Por ello, el componente jurídico debe formar parte de una estrategia integral más amplia, cosa que en Chile no ha ocurrido. Para el autor, la conceptualización de los tratados como santos o intangibles, que maneja la diplomacia chilena, es de índole más idealista que realista. La realidad indica que Bolivia y Perú han tenido la voluntad de “tangibilizarlos” y eso implica la necesidad de enfrentar una realidad política y diplomática, que no soslaye la negociación.
