The nice thing for Ukraine and bad thing for Russia is that everyone involved in planning and executing the mission is still alive having only briefly risked their lives to assemble the containers inside Russia. The mission apparently took 18 months of preparation. But what about the next one, 9 months, 6? What lessons did they learn? Sure, Russia is going to be keeping closer eye on containers now but it's a big country with lots going on that bad actors can blend into.
