Military intervention is never "humanitarian" even if there was will to be...

Indeed, wars are in many ways the opposition of human rights.

The Universal Declaration of Human Rights

Everyone has the right to life, liberty and security of person.

In wars, wearing a uniform removes your right to life and grants you the right to take life clad in other uniforms. Also wars are destructive, not constructive. They can destroy the current structure, but not build a new one.

Cause one have to make a choice which side to take and while we are saving some people we are killing others.

So one side has to be chosen to take over control, unless the military power is ready to by itself occupy the society intervened into.

But it is always some hidden reason for military intervention...follow  the money.

I think this is a more real description of the relationship between military expeditions and the will of the people than the one in the diary.

European Tribune - Liberal Interventionism, Human Rights, and Political Philosophy

by-standers in powerful country A have a couple choices [...] use military force to stop the atrocities, or to punish the guilty

Either these by-standers are ordinary people, in which case they are unlikely to wield any direct influence over military force (in particular if it is powerful), or they are an elite that controls the state apparatus, in which case they are unlikely to do little unless it furthers their position.
