the GBU-39 is not banned
After the large scale usage of GBU-39 against civilian targets in Gaza it was proven that this bomb uses depleted uranium which has lots of side effects. Usage of such bombs are internationally banned. In Europe for instance the resolution to ban them was passed on 22 May 2008 (Document 52008IP0233).
Go troll somewhere else Franky.
Wrong.
The GBU-39 can carry several types of warheads and only 1 of them is controversial: It called
DIME and does NOT contain depleted uranium - it contains micro particles of a (different) dense inert metal. The debate is not about banning the GBU-39, it is about banning DIME wareheads. From the wiki article:
To date, tungsten alloy (heavy metal tungsten alloy, or HMTA) composed of tungsten and other metals such as cobalt and nickel or iron has been the preferred material for the dense microshrapnel or powder.
That said, using DIME warheads nonetheless does cause serious bio effects to folks that are not immediately killed by the bomb:
Tungsten alloy carcinogenicity may be most closely related to the nickel content of the alloys used in weapons to date; however, pure tungsten and tungsten trioxide are also suspected of carcinogenic and other toxic properties, and have been shown to have such effects in animal studies.[6]
In 2009, a group of Italian scientists affiliated with the New Weapons Research Committee (NWRC) watchdog group pronounced DIME wounds "untreatable" because the powdered tungsten they dispense cannot be removed surgically.[7]
