[Warning: despondent and probably unhelpful post. Don't feel you have to read.]
I've been expecting civil unrest or external war since a few years back.
To the point that I said out loud during the 2014 centenary of the start of World War I, that I hoped we'd get to the centenary of the armistice without embarking on another one.
In the UK I've watched things cooking up since the demonising of the disabled began. And then into the bank crashes. And then idealogical austerity. Divide and rule, all with an increasingly vicious tone of beggar thy neighbour.
I wondered how we would move from the UK priding itself on a self-image as a caring, forward-looking country with the glow of having "done the right thing" wrt Jewish refugees, of looking after the sick and disabled, of promoting women's rights and gay rights - what would move us from that culture to one of unashamedly throwing out those values, and jingoistic enthusiasm for external battles. The propaganda which was used to oil the cuts to disability services has certainly contributed to it, and was red-flagged by many of us at the time: "disabled people are scroungers and harm your economic chances and you have permission not to care." Then rinse and repeat for any group of your choice.
I don't think we're there yet with an external enemy: Daesh is too nebulous to engage with satisfyingly; Russia might yet provide the bogeyman, to whom outraged national pride has to give a bloody nose while of course being home by Christmas - not.
But in terms of bringing things up to be ready for kick-off, I saw the war in Syria worsening and UNHRC saying it no longer had the funds to feed the refugees in Jordan and within Syria, and thought, "Yep, mass population movement: that might do it. Direct effects on nearby countries; knock on effects elsewhere."
Once countries are at boiling point, it takes barely anything at all for a country to go pop at another country: a government wants to unite its internal audience; individuals are stressed and fearful and want someone to take it out on. Or they identify an enemy within, like Jewish people, and round on them ferociously to exorcise the national stress.
On a historical level, it's all very, very familiar.
The predictability doesn't make me any happier about any of this.
I don't think there's much we can do to stop it. I see a real appetite for conflict and hatred. People enthusiastically drawing up their In-Groups and Out-Groups, their belonging and their hate. Talking of bombing Syria after the Bataclan attacks, because it will "make them feel better" (not because it will make the UK safer or give relief to the victims of Daesh or the like).
There isn't some magic solution to head this off, because this isn't being caused by one issue. I saw this coming BEFORE Syrian refugees were on Europeans' radar.
