Let's Give Them an Olive Branch in Return

I just had a marvelous thought. Why doesn't the United States respond to the perceived (although I missed it) olive branch, supposedly extended by Raul? I can see it now. We would be delighted to enter into negotiations (just negotiations) on an equal footing, ascribing to the Cuban government all the dignity it requires. Unfortunately by law, the United States cannot have any dealings with Raul, so in order to better the lot of his countrymen and to further the interests of his country, Raul needs to remove himself permanently. Venezuela sounds about right.
