We put unjust wars first because most wars are unjust. War mentality relies heavily on using the human herd instinct to shame the soldier into fighting the unjust war. One is told that they should be a brave soldier and fight for some cause that is in fact a bullshit cause. They are promised glory and honor and that if they die, then their memory and their families will be attributed with greatness because the honorable brave soldier gave his live for the supposedly noble cause. But often the noble cause is just some oil company trying to set up an unelected puppet president in order to steal oil from a less powerful group of people.

The Realist is required to think things through and to determine as best he can what the truth is and if the war is unjust, to resist the war and to refuse to participate in it. In an unjust war the Realist is expected to fight against the war effort - to protest - and to make the truth known to as many people as possible.
