Sometimes an invasion is a part of defence response. I am surprised this concept is new to some people.As I said, Putin would need to be a willing participant for this "Trap" to work. None of what it does cannot happen unless Putin himself decided to invade Ukraine. Unless you are saying the West somehow forced Russia to invade Ukraine, this being a trap does not really make sense.
This is not about Putin miscalculate, he has to when he invades, this has to do with he chooses to invade anyway. Unless he thinks the West is going to do absolutely nothing and Finland or Sweden would not care about the status quo changes. Both of which you have to be extremely naive to believe so.
