> And US sanctions as written do not allow us to provide commercial services or services which could be used commercially to sanctioned countries.

This statement is so wide-sweeping as to be patently false. Some sanctions target specific activities. Others target specific entities that may or may not be entire countries. Many sanctions do not apply to information and communication services. To make such a wide statememt as you did suggests you're oversimplifying to placate the masses. Either way, not a good look.
