My grandfather was killed by agent orange. He wound up with some extremely rare lung condition, but according to the VA, it wasn't the right lung condition so they denied his claim. He didn't die in his 80s, he died in his early 60s. The VA also claimed he was never exposed because he wasn't in one of the units they claim were exposed, that's the other game they play. He was in a mobile unit that was sent to various places in theater, so the government doesn't have the documentation of where they actually were, but claims they know he wasn't exposed. He told me first hand he woke up one morning and the jungle outside the base was completely gone. We don't know what agent orange did to people. Agent orange wasn't even the only defoliant used. How much of it was stored improperly? How much of it was contaminated during manufacturing with other compounds? Fortunately, we still use 2,4-D, half the mix of agent orange, so we all get to find out first hand.
