The co-operation between Bull and Saddam Hussein was an immediate threat to Iran and Israel, as Iran had endured an eight-year-long war with Iraq, and Israel had previous military engagements with Iraq during the Arab–Israeli war.

As for Iran, it was under threat from both Bull's supergun and his re-designed Scud missiles.
