Be_in_agreement_on_action

Two (or more) people (the Parties, also encodable as Party_1 and Party_2) have an agreement. Both sides are construed as having a commitment to an Obligation--the relationship is understood to be symmetrical or reciprocal. Instead of a specific mention of the Obligation, a Topic expression may be used to indicate the domain covered. The US and Russia have an agreement to share early warning data on missile launches.
