Although it was in the immediate interest of both Israel and Iran that Bull discontinue his co-operation with Saddam Hussein, he had worked for many different parties in many critical defence projects, and had become both an asset and a liability for several powerful groups simultaneously.[39] Due to Bull's past ventures, it has been speculated that besides Iran or Israel, the CIA, MI6, or the Chilean, Syrian, Iraqi, or South African government could have been behind his assassination.
Like, obviously the part about getting killed by probably the mossad for helping Saddam Hussein try to build space guns is the headline, but my favorite bit is that the paragraph about him being awarded US citizenship through an act of congress (for some reason) is followed immediately by the one about him being imprisoned by the US for illegal arms dealing to South Africa and then getting dinged by Canada right after that for illegal arms dealing to China.
Anyway, space guns seem cool, people should fire comically big guns at the sky again (I am not a space scientist, this is not space science advice)
