Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Since the end of the Cold War, walls, fences, and fortifications have been constructed on interstate borders at a rapid rate. It remains unclear, however, whether these fortifications provide effective security. We explore whether border fortifications provide security against the international spread of violent militancy. Although barriers can reduce the likelihood that militant activity diffuses across international borders, their effectiveness is conditional upon the roughness of the terrain on which they are built and the level of infrastructure development in their proximity. Barriers require intensive manpower to monitor and patrol, and so conditions like rough terrain and poor infrastructure render security activity more difficult. However, rebels and other militants prefer to operate in such difficult areas, ultimately reducing ' .
