Gallipoli: I like Australian history. Well, at least from 1901-1945. It'd also be nice to see it for my own two eyes. And puke afterwards from the bloodshed.
Kokoda: Again, for my interests, as well as the tactics used by the 'chocos' to fend off the Japanese.
D-day: I'd actually like to see D-day not bastardised by movies and TV. Pure, unadulterated D-day, free from any countries interpretation of it.
The dropping of Fatman and Little Boy: This event caused so much destruction, not only in terms of lives lost, but it also heralded an age of fear, and age where pressing the wrong button would mean that humanity would cease to exist. Pure curiosity wants me to see it.
Indian Independence (specifically Ghandi): I'm talking about what led up to India's (and Pakistan's) independence. I'd like to see how Ghandi used peace to achieve his goals, and how it was a success.
