Nationalism is often conflated with patriotism.
Patriotism is defined as the display of pride and love in one's country coupled with the willingness to defend the nation-state.
Nationalism is love of country coupled with the belief that one's country is superior to others and that the needs of one's country should take precedence without regard for effects on other nation-states.
Xenophobia–the fear or hatred of outsiders–is part of extreme nationalism.

Trump's campaign slogan--Make America Great Again--is viewed by many as an expression of nationalism rather than patriotism because it has been coupled with denigration of other nations.
