Many thanks Clark for your very informative comments. It should not be forgotten that the so-called depleted Uranium weapons have also been shown to involve a nuclear fusion reaction. The range of isotopes found in samples taken from sites hit by depleted uranium weapons in the Iraq war has been shown to be incompatible with any description of the action of the weapons not involving some kind of thermonuclear reaction, and most consistent with a thermonuclear fission reaction. Hence the sickness of many Iraq war veterans is unsurprising. The British and US militaries have kept virtually all the scientific research on depleted uranium secret, because the legal reality is that depleted uranium weapons are nuclear weapons, and their use on the battlefield is illegal. The devastation of society due to nuclear fallout in all countries where depleted uranium has been used – including Iraq, Afghanistan and Serbia – is beyond comprehension.
