Question 1: rationale behind regulation of armed conflict
Question 2: Briefly outline fundamental principles governing conduct of warfare on land.

Principle of Discrimination or Distinction
The principle of distinction is sometimes referred to as the “grandfather of all principles,” as it forms the foundation for much of the Geneva Tradition of the law of armed conflict. The essence of the principle is that military attacks should be directed at combatants and military targets, and not civilians or civilian property.

The test to determine if an attack is proportional is found in AP I, art. 51(5)(b): “[a]n attack which may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects, or a combination thereof, which would be
