Some democratic peace researchers have been criticized for post hoc reclassifying some specific conflicts as non-wars or political systems as non-democracies without checking and correcting the whole data set used similarly. According to these authors, the theory can explain the empirical phenomena previously explained by the earlier dominant research program, realism in international relations; in addition, the initial statement that democracies do not, or rarely, wage war on one another, has been followed by a rapidly growing literature on novel empirical regularities (Ray 2003, Chernoff 2004, Harrison 2010). Supporters of realism in international relations in general argue that not democracy or its absence, but considerations and evaluations of power, cause peace or war. ./cache/en-wikipedia-org-4027.html ./txt/en-wikipedia-org-4027.txt
