I posted this on Dec 10, but now have to say, given his & your continued exploitation of this young man's death, the Father's & your motives are entirely political.
His death was the sole responsibility of the terrorist a fact you & his Father need to recognize.
Notwithstanding the tragic death of his Son, it's he who has politicised his death.
Let's be kind in the situation & agree his judgement has been affected by grief.
