Step-by-step explanation:
The key career field reaction to the Khobar Towers Bombing was an increased focus on counterterrorism efforts and a strengthening of security measures. Following the bombing, which took place in 1996 and was carried out by a Saudi Hezbollah group, the United States and its allies recognized the need to enhance their abilities to prevent and respond to such attacks. This led to an expansion of intelligence gathering and analysis, increased cooperation and coordination between law enforcement and intelligence agencies, and the development of new technologies and strategies to detect and deter terrorism.
