What Senator Cotton did is a gross breach of discipline, and especially as a veteran of the Army, he should know better… I have no issue with Senator Cotton, or others, voicing their opinion in opposition to any deal to halt Iran’s nuclear progress. Speaking out on these issues is clearly part of his job. But to directly engage a foreign entity, in this way, undermining the strategy and work of our diplomats and our Commander in Chief, strains the very discipline and structure that our foreign relations depend on, to succeed.
