"Father, how far are they from Baghdad?" asks Husam's 14 year-old son as he sees the military helicopters fly overhead, bringing the injured back from battle. It's a question that makes him very uncomfortable. The "they" is the ISIS, otherwise known as Daash or Islamic State, and reputed to have already infiltrated the Iraqi capital with sleeper cells. Husam could leave. Like other UN staff he's been offered evacuation. And having seen fellow workers lose members of their families and having had to three times repair his house for explosion damage, you wouldn't blame him.
There are hundreds (if not thousands) of accounts on Twitter that promote and justify killings of civilians in Iraq, as well as Kurdistan. Some of the accounts tweet in Arabic, but have a English disclaimer that says, "Not IS". Other accounts are promoting IS ideological beliefs and urging others to join IS.
The psychological trauma inflicted when children lose their parents, see their homes destroyed, or experience torture, is not easily alleviated, particularly when they have to remain in the stressful and unfamiliar environment of a refugee camp. Save the Children's staff see the signs of this in places like Syria and Gaza, from night terrors and bed wetting to children who refuse to speak.
The charges against David Cameron over his Iraq policy are well founded. But there are extenuating circumstances... It is time for a root-and-branch review of the principles of British foreign policy, so that they reflect two essential things: the world as it is and not as we would wish it to be; and the British national interest. Or, to put it another way, don't do nation-building and don't intervene in other people's civil wars - we usually make things worse, as in Iraq, and the waste of blood and treasure is unforgivable. If this means hobnobbing with dictators, so be it. Only genocide and threats to world order merit military intervention, as with IS.
