Moreover, they frequently are not engaged in "defensive" missions, but are instead part and parcel of Washington's arrogant force projection around the world.
The traditional missions were not always sensible or achievable ones, to be sure.

Not surprisingly, that mission proved to be utterly futile and frustrating.
