The other nation Offers Protection

After the other nation claimed their right to eastern Poland, we assumed another attack as impending. However, a recent offer from the theirs indicate otherwise. Apparently, provided we cede the claimed territory, they are willing to let us join them in an alliance. Furthermore, they promise that in the event of a war with Germany, we will be compensated for the loss by being granted new land in the west. While this may be a better offer than we expected, we can't know if this supposed future war will ever be pursued. Perhaps the other nation is only looking for an easy land grab and forcing us into their sphere of influence. Nevertheless, it may be the best protection we can count on.
