We were warned, we just didn't want to know.
'Jihadists have repeatedly threatened to strike the UK in recent years. In April last year, Islamic State released a video, praising the attacks in Paris and Brussels and promising London, Berlin, or Rome will be next.
The video, titled, "Fight them, Allah will punish them by your hands" after a Quran verse (009:014), quotes another verse (191-193) calling on Muslims to "kill [infidels] wherever you find them" and promised more "dark days" for Europe.
"Nations of the cross this message is for you. Know that your options are few: either you join Islam, or pay tribute, or face the war," the narrator added.'
They mean it, regardless of what moral relativists, Marxists and BBC 'experts' tell you, the Islamists really mean it. They want us kufr dead and they've got the Koranic verses to support their actions.
