President Obama's solution(s) to all crises is rhetoric. His line(s) in the sand disappear and are replaced with just what, more rhetoric. This works for him at home where he has the veto to back his speech,..but in foreign affairs it, more often than not, takes action(s). He backed down in Syria, not once but multiple times, was saved by a Kerry misspeak and Putin's political savvy. Now adopting Rouhani's claim to moderation President Obama can start afresh with renewed rhetoric re: Iran's nuclear development, all the while steering clear of what should/must be done immediately in regard to Iran's impending nuclear capability. Heard of Korea's status in nuclear development lately? President Obama avoids foreign confrontation(s) at all costs, he is incapable of dealing with it. Russian President Putin has shown all world leaders the path through and around our President,....simply change the conversation.
