They are a threat to U. S. in the sense they do not align themselves well to U. S. interests and have lots of nukes. But they are no Germany&Japan level threat; sure, their actions and demands need to be taken seriously, they cannot be labeled as 'terrorist', but at the same time, decades after 2nd world war, they did not begin any large scale military attack on the West, and there is no indication they desire/plan to do so.
