KEVIN MARTIN – This week’s trip by President Joe Biden to Israel, Palestine and Saudi Arabia offers several opportunities to “go big.” With his critical domestic agenda mostly stalled at home, his trip to the Middle East offers potentially historic opportunities for foreign policy breakthroughs that would dramatically increase regional and global peace and security. The president should go big and go bold, and add at least one stop to his itinerary – Tehran. He has several opportunities to make some lemonade out of lemons, if he displays unusual boldness.
