I know that "change war for schools", "change war for smiles" is very simplistic, but why not? I like the deliberate naivety of the artist. It reminds me of John Lennon's "Imagine", a song which for me at least is in equal measure annoyingly simplistic and dreamingly uplifting.
If only we could change war for schools, if only we could change war for smiles. Of course there is hope:
He will judge between the nations and will settle disputes for many peoples. They will beat their swords into ploughshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war any more.(Isaiah 2:4)
