Given the level of the political debate in the US regarding the negotiations with Iran, not to mention the ridiculous letter sent to Tehran, this article is all the more relevant:
Rather than accomplishing any of these things, Washington seems to be trapped in a never-ending back and forth, in which sloganeering substitutes for analysis and political point-scoring is elevated above policymaking. It’s a dismal spectacle, and if it goes on indefinitely it will exact an increasingly high price. Not the sudden collapse of Pax Americana, perhaps, but the gradual undermining of it.
