Final answer:
President Barack Obama focused his counterterrorism efforts on Al Qaeda and its leader Osama bin Laden, following a hybrid approach in foreign policy to address terrorist threats and supporting the mission that led to bin Laden's demise in 2011.
Step-by-step explanation:
The focal point of President Barack Obama's efforts against terrorism was chiefly on the network led by Al Qaeda leader Osama bin Laden, who was directly responsible for the September 11 attacks. President Obama's administration continued the global war on terror, which included the critical mission that resulted in the successful raid on Osama bin Laden's compound on May 1, 2011. This operation was a significant aspect of Obama's foreign policy, aimed at dismantling Al Qaeda and combating terrorism that posed a threat to global security.
Additionally, President Obama adopted a hybrid approach in foreign policy, which combined liberal internationalism with neoconservative tendencies to selectively engage in military actions against terrorist threats in other nation-states without explicit approval. This policy was trusted to deal with new kinds of enemies like Al Qaeda and ISIS that defied traditional categorizations and operated across national borders.
While President Obama's policies and actions in the war on terror were met with both support and criticism, the targeting and elimination of Osama bin Laden was perceived as a significant achievement in the United States' efforts against global terrorism.
