(CNN) -- After nearly going to war last year over a Colombian military raid inside Ecuador, the two nations seemed to be patching relations when their foreign ministers met a few weeks ago. Then an Ecuadorian judge issued an arrest warrant this week for the head of the Colombian armed forces, pushing relations back one giant step. Colombian Gen. Freddy Padilla, the armed forces chief whose arrest is sought, canceled a meeting scheduled for Friday with Ecuadorian Gen. Fabian Varela. Padilla thought he might be arrested if he traveled to Ecuador. It's not the first pothole on the path to normalization. Ecuador previously issued an arrest warrant for former Colombian Defense Minister Juan Manuel Santos, who held the post during last year's raid.
