Research Task: Why does Don Pedro dislike his brother?

In order to justify my hidden anger towards my brother I have to have a strong reason in order to make sure my there is truth behind my actions. I have done some research into friendly fire/blue on blue attacks.

friendly fire

noun

MILITARY

1. weapon fire coming from one's own side that causes accidental injury or death to one's own forces.

During a very heavy raid one night Don John and has squadron devise a plan to loop round the back of the target and shoot Don Pedro and his men in the back and then blame it on misinformation from the strategy department. This would effectively kill Don Pedro and allow Don John to get away with murder without being court marshalled. This was all going to plan until Claudio tipped Don Pedro off about the plan and allowed him to stop it before the mission began. However Don Pedro never reported this to the military police because it would disgrace the family name and he still had a sense of loyalty towards his brother. It took awhile but they final reconciled just before the end of the gulf war but of course the tension still remains.

This article details some of the worst cases of friendly fire, they usually always happen by accident however someone could utilise this and use it as an excuse to end the life of someone else and then blame it on a misfire or miscommunication.
