This EO is scary as hell .. I’m not too worried about them trying to arrest Bush/Cheney they do have secret service protection at all times and I dont think Dear Leader is that stupid to turn a blind eye if Interpol were to ever target those two. That being said, the only reason I can think of for such an order is to remove opposition without the intereference of the American proccess
His EO certainly bypasses Senate ratification of the UN treaty. Perhaps Obama’s trying to make up for his failure to commit the US to the COP15 climate treaty.
