Mr Putin is very close to the Russian Orthodox church leaders and is, with their advice, sadly clamping down on evangelical out-reach and churches. (Seen as competition by the eastern patriarchs).
* I write to suggest something else is going on - perhaps. The grabbing of ports could be to secure dominance on the Black Sea. Mr Putin may ultimately, have ambitions on far-off lands. One of these could be, the Turkish city of Istanbul. Istanbul is sited on both sides of the narrow Bosphorus river straights; the only maritime access between the Black Sea and the Mediterranean. Apart from it's strategic importance militarily, it has massive spiritual significance too. At the end of the first world war Russia had designs ("The Constantinople Agreement") on taking back the city of Istanbul for the orthodox church, so as give it back the name Constantinople, but was thwarted by rising Turkish leader, Ataturk.
Constantinople was the eastern Roman Empire and second "leg of iron" in Daniel 3:1. It would be prophetically interesting if it were "reclaimed" in the (near) future?
All just supposition at this stage, but God is unpacking His word day by day.
"Wars and Rumours of Wars" - just like Jesus said.
