According to The New York Times, the level of Iranian surveillance was particularly alarming. Tehran's operatives possessed highly detailed information about Trump's location in Ankara, including the specific floor of the building where he was staying during the summit. During a security assessment in the area surrounding the summit venue, authorities identified an individual armed with a shoulder-fired anti-aircraft missile, transforming the threat from theoretical to immediate. The gravity of the intelligence led the president and his senior advisers to authorize an extraordinary evacuation operation. The Secret Service and U.S. military made an unprecedented decision: to smuggle the president away from both Iranian surveillance and the traveling press corps.
