Cover art for Love's Sweet Exile lyrics by Manic Street Preachers

I thought this was about imperialism. From any 1st world countries viewpoint, percieved 'threats' in the form of extremist religions or simply refugees or asylum seekers are very powerful. It's saying take action against anyone or anything that could potentially affect what we take for granted. The 'leave this country' line I think refers to supporting aggressive or military action abroad, but not close to home. NOT 'leave this country' as in 'get out!.'That's what I'm hearing anyway.
