It may surprise you to know that Wal-Mart, the world's largest retailer, failed in its attempt to enter the German market. In fact, it cost about $1 billion USD for Wal-Mart to ultimately exit the country. Please Google this topic and summarize your findings. I think you will find this very interesting.
If you were Wal-Mart's competitor (ex. Target) - how could you benefit from understanding the Wal-Mart case if you were considering entering Germany or another country? Could you use this information to make good decisions?
