It didn't start that way but the Syrian uprising has been sucked into a sectarian conflict which dwarfs our own little differences and has global implications.
Like people here, most Muslims want to live at peace with their neighbours and build a better future for their children. Yet the underlying dynamic is conflict between adherents of the faith's two main sects – Shia and Sunni.
Outsiders should not simply pick a side in this wider struggle. Sunnis control Saudi Arabia and the gulf. That creates influence with oil importing countries; America and Britain regard gulf states as a key regional allies and export markets. Yet Osama bin Laden and Saddam Hussein were also both Sunnis, and Sunni extremists still control Al-Qaida.
Bashir Al Assad, the embattled Syrian dictator, is a secular Alawite, a Shia breakaway, which is why the Shia leaders of Iran support him. They are hoping for a Shia crescent running through Iran, southern Iraq, Lebanon and Syria.
Western powers need to be very careful about getting sucked into a struggle which will take decades to resolve itself and in which no side is all good or all bad.
The trick is finding a way to help those who are suffering and to make long-term friends in the region. Aid, trade and diplomacy must be the primary tools in that task.
