[Iran's Top Security Official: The US Will Leave; Gulf States Should Promote Regional Cooperation] Rezaei, Secretary of Iran's Supreme National Security Council, stated in an interview: "The US and Trump will leave. Everyone knows that the US economy is actually on the road to collapse. The US will not be what it is today in the next 10 years. But we and the Arab countries will continue to exist. We are the ones who must solve the problems in the region. We must establish a security mechanism in the Persian Gulf. We must establish economic cooperation agreements and become friends in the region. We are one family—the Persian Gulf family. We have eight countries, and we must focus on reconstruction and economic development, strengthen cooperation, participate in each other's investments, and even establish a single currency and a unified common market."
