Bloomberg: “As President Donald Trump continues to suggest a deal with Iran is close, he finds himself caught between two extremes: Tehran’s demand for financial relief and an end to attacks, and pressure from Republican hawks to “finish the job” — or at least not to sign a bad deal.”“The competing pressures have, so far, kept an agreement to end the war out of reach. And they have resulted in the administration’s swinging between promises of an imminent deal and threats to resume military operations.”“Adding to the challenge are his own comments over the years lambasting his predecessors for signing or considering deals similar to the one that has the best chance of success.”
