It was not my intent to make it seem that I had made any insinuations on your part.  It was more that I wanted to express an alternate possibility rather than the nefarious one that was being discussed. 

It seemed that the only scenario involving pressure or coercion on the part of the U.S. being discussed was one of compliance by the company rather than a range of possibilities.  Events in life do not always happen neatly and predictably.  If we are going to discuss outcomes, we need to talk about more than one.
