When does an anti-Government uprising become a civil war? Can the rebels wage a proper united campaign? How will the West proceed in its dealings with Libya and the wider North Africa Middle East (MENA) region?
"Is it ever right for Christians to support military action in places like Libya?" That was the question posed to me on Premier Christian Radio this morning, alongside the pragmatic issue of what is happening following the Western bombing raids and what the wider implications are.
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.
