Can you reship/re-export packages to Cuba, Iran, Iraq, North Korea, Somalia and Sudan

Shipito shipping forwarder forces all its customers to agree with the following in every customs declaration:

I hereby declare that these specific commodities are being exported from the United States in accordance with all applicable United States export control laws and regulations including regulations administered by the U.S. Department of Commerce, U.S. Department of State, and the U.S. Department of Treasury. As a customer of Shipito and/or Eastbiz Corporation, I agree not to export, re-export, or transship these commodities to any country that the United States has imposed an embargo or trade sanction upon, including but not limited to Cuba, Iran, Iraq, North Korea, Somalia and Sudan or any destination for which United States requires an export license without first obtaining such license(s). Diversion of these commodities contrary to the United States law is prohibited. Any and all export license requirements are the sole responsibility of the individual and/or entity in contractual agreement with Shipito and/or Eastbiz Corporation.

It looks even more stupid considering the fact that most products sold in the USA and purchased there by the customers from the rest of the world are actually produced in Asia (mainly in China). Nevertheless if you buy in the USA something manufactured in China and then reship / re-export it to Cuba, Iran, Iraq, North Korea, Somalia and Sudan, you will break the US laws. And that means if one day you visit the USA, its authorities can arrest you and jail you for breaking the law!
