Her agenda (ending the Iraq War and holding the war criminals accountable) is not personal to her (it is shared by hundreds of millions of people around the globe), indeed, it has nothing to do with her: her son is dead, he will not be helped by ending the Iraq War. If there is any personal component to her agenda, it is a purely fantastical one, namely, a distraught parent exacting "just revenge" upon at least some of those responsible for her misery.
But, I guess everyone has to have a personal agenda just because they disagree with something you believe in.
