Daily Telegraph har intervjuet et knippe briter som har meldt seg som frivillige til peshmerga-styrkene i Nord-Irak. De er ikke så mange. Et 50-tall. Det er langt flere på den andre siden: Britiske muslimer som kjemper for IS.
De er så mange at de er flere enn de som dro til Spania for å kjempe for Den internasjonale brigaden fra 1936 og fremover.
Ben is one of an estimated 50 Britons who have gone to Iraq and Syria to fight with the Kurds against Isil. He left behind his fiancée and baby daughter, now 18 months old. He bought his own kit and weapons, organised travel from Scotland, and is paid only in food and gratitude.
On the other side of the battle line, it is estimated by UK security services that more British Muslims have joined Isil than are serving in the British Army. Not since the Spanish Civil War, when about 2,300 British volunteers – most famously, George Orwell – went to fight Franco in the 1930s, have so many volunteered.
Det bør utløse noen tanker.
