No one has any real idea inRP why it started, it actually started because RM found LSF testing on nomad stuff and basically demand Liberty to stop, Liberty in return basically told Rheinland to screw off and continued on. Rheinland during that go upset and tried to invade and destroy Alaska which failed causing LN and RM to go into battle basically. This trade thing won't work till either
A: Liberty stops their nomadic researching and lets Rheinland officers check
OR
B: Till Rheinland gives in to Liberty or becomes part of another house entirely (Say like with Gallia or something)
