War, is one of the 4 themes that I will persent on Friday. It definitely is a wide-range topic for doing research. First, I have done a mindmap on topic "War", expanded ideas from 5 directions. It includes gains and adverse impact form wars, politics in wars, civilians in wars and armaments may use or developing in wars.
Also, there are pictures/photographs/concept arts below are really helpful to understand "War". A few shot videos are useful to explore and understand what circumstance of people during wars; how powerful and the perniciousness of nuclear weapons, how could the WW1 changed the world and history , and weapons used in ancient Chinese wars.
The mind map includes some ideas on gains (profit) from wars and 'adverse impact'. Also 'Politics' are important to understand how politicians controlled states and circumstance of people during wars. 'Armaments' to focus on different types of weapons in militaries from ancient period to modern world.
War is a state of armed conflict between states, governments, societies and informal paramilitary groups, such as mercenaries, insurgents and militias. It is generally characterized by extreme violence, aggression, destruction, and mortality, using regular or irregular military forces.
