As Per 3.2. on Declaring conflicts.
Quote" 3.2. Declare conflict (Shares 3.2 with conflict resolution chart.) During the conflict phase, each player is granted one opportunity to declare a military conflict and one opportunity to declare a political conflict. These conflict opportunities alternate between players with remaining conflict opportunities in player order until each player has declared a conflict or passed on each of his or her conflict opportunities. A player’s military and political conflicts may be declared in either order during the round. When a player has an opportunity to declare a conflict, that player may:
◊ Declare a military conflict, or pass the opportunity to do so.
◊ Declare a political conflict, or pass the opportunity to do so.
If a specific conflict opportunity is passed, the player forfeits his or her right to use that opportunity this phase."
