I can answer that question.
We've had two meetings with Saleem Sattar, the director general of environment and sustainability at DND. He started off by giving us a PowerPoint-type presentation on the two and a half barrels the Americans sprayed there in 1966 and 1967, over a seven-day period.
He did not mention or allude to the fact that DND sprayed 6,504 barrels of the exact same chemical starting back as early as 1956. We asked him about that.
