In a brief radio address after order had been restored, Diệm dismissed the attack as an "isolated act" and attributed his escape to "divine protection". He visited the soldiers wounded in the attacks, and also promised the rebel pilots' colleagues that they would not bear any responsibility for the bombing. American President John F. Kennedy promptly sent a message denouncing the attack as a "destructive and vicious act", and expressed relief that Diệm was "safe and unharmed". US ambassador Frederick Nolting determined that the attack had been the result of "two isolated cases" and opined that the incident did not represent widespread dissatisfaction with the regime. The absence of a VC reaction led Nolting to label the bombing as a "limited scope, anti-Communist assassination attempt". Diệm was praised for outwardly projecting a calm demeanour following the attack, and he moved to temporary government accommodation usually used for foreign dignitaries and visited Bien Hoa Air Base.
