No, used literally "war" (without modifiers like "civil", etc.) refers to a thing waged between countries. War on concepts are a metaphor, not a literal description, that puts the—actual or for-propaganda-purposes—goal of a set of policies front and center rather than actual policies ((which may or may not be or include literal wars on countries; consider the range from the "War on Poverty" through the "War on Drugs" to the "Global War on Terror".)
