To be fair, Waters doesn't need to explain what he's trying to do, as even the ADL seemed to have understood his stage show before they then pretended not. But Sideline have reported his formal response:
"Contrary to Mr Foxman's assertion, there are no hidden meanings in the order or juxtaposition of these symbols. The point I am trying to make in the song is that the bombardment we are all subject to by conflicting religious, political, and economic ideologies only encourages us to turn against one another, and I mourn the concomitant loss of life. If 'The Wall' show did have a political message it was to seek to illuminate our condition, and find new ways to encourage peace and understanding, particularly in the Middle East."The other charge - that Waters deals with global politics in such a broad-brushed way that it would make a sixth form common room cringe - remains on the record for now.
