Halliday & Matthiessen (1999: 273-4):
Just one instance, or a few instances, would have little or no effect; but when there is a rather massive frame of consistency whereby the same metaphor, or metaphoric syndrome, extends across a major region of semantic space this must play a significant part in our overall construction of reality. So, to cite another example from Lakoff s work, in his (1992) study of the metaphors "used to justify [the 1990] war in the [Persian] Gulf, he identifies a number of dominant motifs — he refers to these as "metaphoric systems" — such as state-as-person, fairy tale of the just war (with "self-defence" and "rescue" scenarios), ruler-for-state metonymy; war as, selectively, violent crime, competitive game or medicine — all of which he finds to have been applied in portraying Saddam Hussein as villain, Kuwait as victim, and in constructing the concept of "victory" ('the game is over'), of the "costs" of war and so on. Lakoff comments "What metaphor does is limit what we notice, highlight what we do see, and provide part of the inferential structure that we reason with".
