 In some political systems, such as certain Latin American regions, governments have been influenced by military intervention as a result of the government's inability to cope with the strains of modernization.Under the framework of political development as institutional development, political decay occurs when institutions fail to change or adapt when they become unnecessary due to social or economic changes.Dan Halvorson challenges the idea of political decay as an institutional failure by claiming that the idea of political decay is tied to a Western ideal of political institution without taking into account widely-varying cultural institutions and the inability of post-colonial states to adapt to Western ideals.
