That puts you in an awkward position then. You've completely put yourself in a knot. Arabissia accepted aid from Rossiya, and since you are thwarting Rossiyan aid, you are denying respect to your ally. Whether you like it or not, you are an ally of the current government. Whether or not you call it a holy alliance, you are shunning a fellow member country and denying its sovereignty amidst the rest of the DAV, and not to mention the inner brotherhood of the massive Slavic populous in Rossiya.
You practically just turned your back and went renegade.
