What is the defense of superior orders?Why have such a defense? When should the defense be available? What should be done in the case of ambiguous orders or when oral commands
contradict written directives? Must the belief that a superior order is lawful be reasonable?
Should different standards apply to privates than to persons higher up the chain of command?What should a soldier do when he is given an order that he thinks is unlawful?

Currently, as of february 2016, an american traveling in france would be by the exchange rate. the weakness of the euro and the strength of the us dollar means that items in france cost less to an american than they otherwise would. of course, if this trend reverses and the us dollar weakens and the euro strengthens, such as was happening in early 2008, an american traveling in france would have an adverse experience because items would cost relatively more.
