US President Donald Trump’s recent visit to Saudi Arabia is being hailed as a win for both nations. Trump secured a Saudi investment pledge of up to $1 trillion, advancing his campaign promise to attract more foreign investment to the US economy. Qatar on Thursday announced potential economic commitments worth $1.2 trillion, while the United Arab Emirates unveiled its $1.4 trillion investment pledge in March. Energy, defense and technology investments are a clear focus. But just as notable as the trillions of dollars (some new, some old) that Trump's transactional approach tallied up are the geopolitical shifts that underpin them — in favor of regional calm over escalation: Trump in Doha hinted that a long-term deal with Iran was within reach, and in Riyadh he announced a surprise pledge to unwind US sanctions on Syria. Both moves, backed by Gulf states, appeared to sideline Israel.
