Joint Embargo
Adds a new diplomatic action separate from the standard Embargo: Joint Embargo.
After initiating a Joint Embargo, all of your allies and subjects at every level will be forced to embargo the target country and cannot withdraw independently. Their embargoes will only end when the original Joint Embargo ends, or when their alliance or subject relationship with you is terminated.
The mod may not take effect immediately; you may need to let a few in-game days pass.
