True or false: Military planners must consider civilian casualties and destruction when planning operations.

Military planners must indeed consider civilian casualties and destruction when planning operations, as this is a crucial aspect of modern military operations. This consideration stems from both moral and legal obligations under international law, particularly the principles of proportionality and distinction. The principle of proportionality requires that the anticipated military advantage gained from an operation outweighs the potential harm to civilian life and property. The principle of distinction mandates that combatants must differentiate between military objectives and civilian objects, ensuring that operations target only legitimate military targets.

Incorporating the potential impacts on civilians not only aligns with these legal standards but also serves to maintain public support and mitigate backlash against military actions. Failure to adequately consider these factors can result in significant loss of life, negative media portrayals, and long-term geopolitical consequences, such as instability in the region or loss of trust in military forces. This responsibility emphasizes the evolving nature of warfare, where the effects on civilians must be carefully weighed during operational planning.
