A more thorough explanation:

Definition: Paction (pak-shən) is a legal term that refers to an agreement between two nations that is to be carried out through a single act.

Example 1: The two countries signed a paction to establish a joint military base in the region.

Example 2: The paction between the two nations allowed for the extradition of criminals between their respective countries.

These examples illustrate how a paction is a specific type of agreement between two nations that is designed to be carried out through a single act. In the first example, the establishment of a joint military base is a complex undertaking that requires a lot of planning and coordination. However, the paction simplifies the process by allowing the two nations to agree on the terms of the base in advance and then carry out the construction and staffing of the base through a single act. In the second example, the paction allows for the extradition of criminals between the two nations. This is a complex legal process that involves many different steps, but the paction simplifies the process by allowing the two nations to agree on the terms of the extradition in advance and then carry out the transfer of the criminal through a single act.
