Teribus' distinction between "patriotism" and nationalism" is correct.

I would go further in saying that "jingoism" is the particularly bellicose form of nationalism.

As Samuel Johnson famously said, "Patriotism is the last refuge of the scoundrel." (He was referring to insincere appeals to patriotism, not the actual sense of patriotism.)

That doesn't logically entail that all or even most patriots are scoundrels, but it may have helped tarnish the very concept of patriotism, especially since the 1960s.
