The use of depleted uranium munitions has been fiercely debated, with opponents like the International Coalition to Ban Uranium Weapons saying there are dangerous health risks from ingesting or inhaling depleted uranium dust, including cancers and birth defects.
Not that dangerous?
Any heavy metal causes similar issues. Heavy metal will be used, whether it's uranium or something else. Should they just stop shooting?
Unironically yes. A peace deal was in the works last year until, according to the Ukranian Pravda, Boris Johnson pressured Zelensky not to go through with it. This would have stopped the fighting and resulted in some withdrawal of Russian troops, but since the West is more interested in weakening their geopolitical rivals and helping the weapons industry rake in profit than ending the war, they squashed any possibility of that happening.
