The above article was published in the Washington Post. My comment on this interview is that it overlooked an important concept. That we have a (misleading) public narrative based on an apparently false premise. The (misleading) public discussion put forth by the media, politicians, and pundits is that Assad needs to be punished.
But there is a critical step that we need to complete before getting to the punishment step. Mr. Grayson
points out there is NO smoking gun. The public discussion should be on
verifying who used the chemical weapons, not bombing Assad into oblivion
for something that he may not have done.
