The United States Armed Forces needs to have several different ways to keep our country safe at hand. Depleted uranium is one of them. We need to be prepared to react to a threat and as we all know threats come in many different forms. Although using depleted uranium many not be a first resort it should be available.
Yes, it is ethical for the United States and its armed forces to use depleted uranium in ammunition used against other countries, because the United States should have the strongest military in the world. With all of the influence the United States has, and for all of its enemies, the United States needs the strongest and best weapons in order to send the message that it is willing to defend itself at all costs.
Depleted uranium is the best material for ammunition. It is more dense and strong than other metals, so it is a good choice for weapons. There is also no concrete evidence that this material is any more dangerous than conventional metals for the people who are using it. It is a good choice for the future.
No, it isn't ethical for the U.S. Armed Forces to use depleted uranium in ammunition used against other countries. Uranium in any source, shape or form is toxic stuff. We're not using it because it tickles and makes the enemy giggle. It should be outlawed by yet another version of the Geneva Convention.
No, it is not ethical to use depleted uranium ammunition against any other country because it will contaminate their country with toxic materials for years to come. The long-term effects of contaminating the soil and ground water of another country will affect innocent civilians for years after the conflict has been resolved. The repercussions of using this ammunition will last for generations in terms of health problems and birth defects. We must also consider that we are exposing our own soldiers to this contamination as they handle the rounds and also must live in the environment where these rounds have been fired while the conflict is on-going.
