So now Putin can add the USA to a list of about a dozen nations that he has territorial disputes with.
More importantly, if he stationed troops there, would Obama do anything?
The church is currently under the OCA (Orthodox Church in America), which was granted autocephaly BY the Russian Orthodox Church in 1970 by the Patriarch and 14 bishops. Not everyone recognized the status of autocephaly, but the RUSSIANS certainly did, as they are the ones who granted it in the first place.
I very seriously doubt the ROC will even begin to consider this, as it would open a huge can of worms for the synod coming up in two years.
