It most likely wasn’t an errant missile. Putin is probing and making a bigger mess. Then seeing what the response will be. Given that is is Brandon and Scholz making decisions I would not expect much of a change in course.
Russian missiles suck. They really do. The are a little better than a dumb bomb dropped from an airplane when they work. They aren’t as good as US guided missiles.
The Iranian drones are decent though (of course they stole the tech from us via Obama).
