With many Sunnis in Iraq so afraid of arbitrary torture, jailings and killings by government forces that they welcome even Isis's protection, we shouldn't take sides in a sectarian civil war ("Iraqi PM rejects unity plea", The Herald, June 26).

Iraqi forces use the same torture methods as Saddam, shoot protesters and summarily execute suspects; partly Saddam's legacy, partly that of US death squad training continued from El Salvador.

Isis's few thousand fighters couldn't beat the Iraqi army without the support of Sunni Iraqi Islamists, tribes and Baathists, and uneasy Isis allies could change sides if given jobs and government posts. Baathists have already clashed with Isis.

From 2006 to 2009 the US provided pay and weapons to Sunni Awakening militias who had turned against al Qaida. When US funding ended the militias became neutral and al Qaida in Iraq began growing.

Sunnis should also be guaranteed an agreed percentage of army jobs.

The distrust created by Iraqi Prime Minister Nouri Al Maliki's sectarian government also requires a coalition government representing all Iraqi parties. Maliki claims this would be undemocratic. It wouldn't. Real democracy doesn't involve winners and losers. It gives everyone a voice.

Tony Blair continues to be a Siren in denial, calling us to the rocks.

Isis split from al Qaida in Iraq and the Al Nusra branch al Qaida established in Syria. Al Qaida wasn't in Iraq before the 2003 invasion.

Mr Blair's apologists claim the US would have invaded Iraq without British support. Yet US opinion polls before the invasion showed most opposed an invasion if their allies did not support it, while two thirds would support it if US allies did.

Nato governments have been funnelling arms via the Saudis and Jordanians to the so called "moderates" among the Syrian rebels, in some cases just con men selling arms on. Some of these arms ended up in the hands of Al Nusra and some will be in Isis's hands now.

Careless intervention is much worse than doing nothing.
