John McCain’s cancer is one associated with exposure to Agent Orange in Vietnam. It is usually fatal within 18 months of diagnosis, even with the best medical care. The US government is reluctant to admit the link between Agent Orange and the illness. What is our responsibility to the people of Vietnam exposed to that chemical? During the war, we exposed millions of innocent people to Agent Orange and then we exited the country, leaving the survivors to cope. And we did the same thing in Iraq with depleted uranium munitions. Piece by piece, country by country, war by war, the US is destroying the world with our wars. I say it is time to stop the fighting and settle our differences in a civilized way.
