I really like the way Iran sends reminder email about over due payment. First it will ask very politely. If ignored, then she will publicise the facts. If still ignored, it will easily confiscate property at will. Then everyone sit up and listen. The funny part is that whatever it confiscates, it can do it again and again and again until full repayment is made and no army can do anything about it. It was done to UK's Britania, US's marines, UK marines, it has even shut down US $300M hawk drone for infringement on Iranian airspace and US kept still!
