There are those who favor using force to change existing political orders. Force is used to get people to do things they don't want to do. Nobody enjoys being forced in this way. It is interfering in their lives.
Such use of force results in the build up of resentments which spill over into future conflicts. Therefore the use of force contributes to long term unrest and works against peace.
To achieve a peaceful outcome trust and friendship must be built. To use force only delays this process.
