The article tries to offer some reflections about the limitations of what is known as peace, it is focused on four points which have become common places about what could happen if the war ends: 1) peace will lower the violence’s rates; 2) peace will diminish impunity’s rates; 3) peace will create conditions for the economy to improve; 4) peace will open the democracy and participation’s rates will be higher. The methodology used focuses the attention on the analysis of these four common places in some armed conflicts already finished, specially the cases from El Salvador and Guatemala, also referring to internal confrontations taking place outside the continent, like Angola and Liberia. The article tries to think about some situations of violence, justice, economy, political participation, in a post-conflict context. Finally, based on the other countries’ stages it shows the need to plan situations after the end of the war and to face peace, as a desirable end for Colombia, in a realistic and mature way.
