Russian Invasion Planned but Not Completed
First of all, what Russia did in Crimea was planned earlier before the so called "outcries" from troubled Russian speaking civilians of Crimea. Russia stopped all adoption requests and processes for legal adoption of Russian orphans well before this annexation was even a thought in the news.
Most of the adoptions that ceased, we're targeted American and UK adoptive proceedings. That fact along with Russia banning any further adoptions from Western lands tells you everything you need to know about the tensions in the Russia and Ukraine area..
Why?
In my opinion, this was a first step in the preparation process for what Russia was planning. Insuring basically that no Russian child would be put in harms way, the Red Army then went into the actions of securing the Crimea peninsula. The timing could not have been better.
At the very least, the ceasing of adoption was a red flag of major importance, overlooked by the powers that be? Doubtful, Uncle Sam doesn't miss much...or does he? Nawww...
