What operation was described as a multinational and multi-service effort to secure air landing strips in Grenada?

Operation Urgent Fury was a significant military operation conducted by the United States and a coalition of Caribbean nations in 1983 to secure air landing strips in Grenada. This operation arose from concerns regarding the safety of American citizens on the island and the growing influence of communism in the Caribbean. The goal was to restore order and resupply the Grenadian government while ensuring the protection of U.S. nationals.

The operation exemplified a multinational and multi-service approach as it involved not only U.S. military forces but also support from other nations, highlighting cooperation in response to an international crisis. It was one of the key examples of the U.S. military's commitment to intervene in events that threatened regional stability, specifically in the context of Cold War dynamics.

In contrast, the other operations listed are associated with different contexts and objectives. Operation Just Cause focused on the removal of Manuel Noriega in Panama, Operation Desert Shield was aimed at defending Saudi Arabia from invasion, and Operation Restore Hope addressed humanitarian concerns in Somalia. Each of these operations had distinct goals and was undertaken in different geopolitical situations. Thus, Operation Urgent Fury stands out as the appropriate choice for the specific mission of securing air landing strips in Grenada.
