British war's advertisement

I can listen in British radios stations something absolutely crazy and in most of civilized countries against the law. They broadcast appeals of the war with machine guns firing and with very rude speech, "calling" youngsters to the army and therefore to the war. No, I am Christian. But such appeal and "speech" in the media, in very raw way is offensive for normal (and cultured) people. In my poor Portugal any speech or conversation in behalf of violence or war is against the law and very often people is convicted about that. Also is against the God's Law. Why in Queens land war and violence and devastation is officially advertised?
