This morning I turned on my radio to a sick sense of deja vu, with the news of war in Libya. Eight years to the day that George Bush announced attacks on Iraq, a stony faced President Obama did the same as he spoke to reporters in Brasilia.
The recent history of western military interventions in the Middle East is hardly encouraging. Yet British PM David Cameron has clearly been itching to begin the bombing in Libya, and US President Obama has also sanctioned armed action - in spite of serious warnings from advisers in and outside the White House.
Today and tomorrow, 27 & 28 October, are key dates in Christian history. Constantine's 'vision of the Cross' in 312, and his attribution of military victory at the Battle of Milvian Bridge the next day to God, was the beginning of Christendom in Europe - an era which mixed civilisation with bloodshed, saints with militarism, and faith with often brutal sacralised-secular power.
