Russia has recently suffered significant losses in its Black Sea fleet and Crimean air defense network, while two Turkish cargo ships en route to a Ukrainian port were struck. These events don't seem coincidental.Either way, it's necessary to think of counter measures. Finding out from where the drones come is important. Don't forget that Ukraine is capable of hitting targets quite deep in Russia.
So we need to have proper surveillance/ radar system and monitoring in place.
We know that the Russians sabotaged and destroyed the Turkish navy twice during the Ottoman era. If Türkiye is also uneasy about the strengthening Russian naval presence in the Black Sea, we may be in conflict behind the scenes. Another scenario is that Ukraine may be trying to draw Türkiye into the conflict.
