Some thoughts, unrelated to the discussion: the British government is using the new war in Iraq as a smokescreen to direct the attention of the public away from issues like social justice, constitutional reform and unjust government policies like the bedroom tax. There will be far, far more government cuts (genuine cuts this time) and worse as the need to stabilise the zig-zagging UK economy grows. Right-wing political parties like the Conservatives can exploit Islamophobia in their electorates for votes (always a plus) and turn the focus away from things like the EU, which strengthens them against UKIP. Labour will be pushed further to the right as a result to compete with the English electorate, but to be honest I don't think they needed much pushing anyway given that they're already a centre-right political organisation.
Newspapers in the UK, even certain broadsheets are included here, also enjoy a win-win scenario. Their readership is aging as most younger people are looking to social media for their current affairs, if at all. The readership of newspapers has thus become far more conservative; people buy newspapers with scary headlines, they don't want to read anything positive. They want to feel angry about something so they can complain/have something to worry about. This means newspapers can start ramping it up with sensationalist headlines about Islamic extremists on our doorstep; with papers flying off the shelves and the poll figures for pro-war/hawkish/hardline parties like the Conservatives and Labour will go up. So what if decent British Muslim folk get demonised in the process? Every generation needs a bogeyman. Anjem Choudhary has already become the new Abu Hamza for the papers, even the BBC, another organisation which has similar interests to the newspapers due to an aging viewing audience. The defence lobbies (with close ties to the Royal Family) and the military industrial complex that hold enormous influence in the country will also benefit enormously from this war.
Given that newspaper editors and political journalists belong to an elite very closely related to the politicians and political party elites (they regularly cross over) it is no surprise that they work so well together.
Did you notice the kinds of things that started to happen after Osama bin Laden died and the focus drifted away from the War on Terror? People started caring more about the little ways the British government shafts them, across the length and breadth of the Isles. The far-right, such as EDL, Britain First and other organisations, were suddenly the terrorists; those who attacked mosques while our Muslim communities gained public sympathy. The Scots suddenly decided to have an independence referendum too - another little example of the kind of thing people in the UK would start debating if convenient bogeymen like the Islamic State and Al Qaeda weren't present.
There's something we tend not to learn in history in schools in Scotland. In 1914 a bill was being debated in the House of Commons to give devolved powers to Scotland similar to that of Ireland. We would have gotten it if we hadn't been dragged into the First World War by the elites. Some things never change.
