Has democracy ever gone to war with another democracy or never gone to a war ‪?‬ Has Democracy ever gone with a war with another democracy or has never gone to war ?

Ram and Rahim read an article. It showed that no democracy has ever gone to war with another democracy. Wars take place only when one of the two governments is non-democratic. The article said that this was great merit of democracy. After reading the essay, Rajesh and Muzaffar had different reactions. Rajesh said that this was not a good argument for democracy. It was just a matter of chance. It is possible that in future democracies may have wars. Muzaffar said that it could not be a matter of chance. Democracies take decisions in such a way that it reduces the chances of war.
Which of the two positions do you agree with and why?
