What were the negative impacts of Australia fighting in the Vietnam War?
You should mention the funding that a country needs to simply be involved in a war. All that money comes from tax payers and is spent on matters overseas rather then domestically. Another point you could mention, of which Agent Orange is an aspect of is simply the physical impacts of war on the soldiers. The harsh conditions they had to fight in and the mental health of the soldiers over time. E.g PTSD. When many of the soldiers returned home, they were treated poorly as apposed to being welcomed home etc. This then drove many into drugs/alcohol etc. Some carried physical scars such as loss of limbs making life more difficult for them etc. Hope this gave you a few more ideas 🙂 Good luck!
