which leader and corresponding nation is missing from the list of fascist countries listed above?

The response for the system know as Nazism is Hitler, Germany.

Explanation:

Adolf Hitler first came to power in Germany in 1933 as Chancellor and then proclaimed himself Fuhrer and stayed in power until 1945 when he lost WWII and committed s.uicide rather than accept capture by Soviet troops. As a form of fascism, Nazism is a form of extreme nationalism that evolved from the ethno-nationalist Volkisch movement that fueled ideas of Pan-German nationalism at the time. The Nazis were influenced by the Freikorps paramilitary groups that emerged after Germany was defeated in World War I. They adopted antisemitism and pseudo-scientific forms of racism and incorporated eugenic ideas into the "cult of violence" which characterized the party movement.
