It had elements from the outset, but the war in Syria is looking more like a war by proxy between outside interests. It may be that it can now only be resolved from outside.
Most wars are proxies to some extent, perhaps the most notorious recent war being the three-cornered contest in Cambodia between 1978 and 1992. Syria is now starting to look like such a multi-faceted contest, but perhaps with even greater potential for complication.
The air attack last week by Israel against a Syrian military target raised the spectre of a wider conflagration. Initial reports said the target was a convoy that was presumed to be carrying guided surface-to-air missiles to Syria's Hezbollah allies in Lebanon. However, reports now indicate the target was a military research centre at Jamraya, north-west of Damascus about 15 kilometres from the Lebanese border.
