You:Wait, ATAPA cannot force you into war?
I thought we all had a mutual defensive pact?
Me in response:ATAPA can not force you into a offensive war, as ATAPA can not act as one to declare war. That was the hypothetical IMO. This is due to the fact that the member of ATAPA SHOULD have known of this defensive pact, and, as such, Party A, the ATAPA member is responsible for Party C declaring war as defense to Party B. Party C DID not "declare" war, as when Party A declared war, by the defensive pact, which activates as soon as Party B enters a war in which he is NOT the defender, Party C was forced into war by Party A, and did not declare
Get it?
