He's a globalist with factories as far afield as China. So he is compromised in his fight for the common cause of small business, trade unionists and those who work the land, against the endlessly interrelated forces of globalisation (by definition including unlimited immigration), American hegemony (with all its wars) and European federalism. That is the trouble with Christoph Blocher.
And of course, if the neocons get their way and bring about the Nazi-led dismemberment of one Latin-Teutonic union in the service of those forces, then the other such union will undoubtedly be next on their hit list. So someone like Blocher is urgently needed. It's just a shame about Blocher himself.
