 At the Stop the War Conference 2009 , he described the wars in Iraq and Afghanistan as " Imperialist war ( s ) " and discussed the killing of American and allied troops by Iraqi or foreign insurgents , questioning whether they were in fact freedom fighters , and comparing the insurgents to a British Dad 's Army , saying : " If you are invaded you have a right to self @-@ defence , and this idea that people in Iraq and Afghanistan who are resisting the invasion are militant Muslim extremists is a complete bloody lie . I joined Dad 's Army when I was sixteen , and if the Germans had arrived , I tell you , I could use a bayonet , a rifle , a revolver , and if I 'd seen a German officer having a meal I 'd have tossed a grenade through the window . Would I have been a freedom fighter or a terrorist ? "
