It's likely they can repair the damage to the bridge in a week --- assuming they are not under bombardment while doing it.
My question is --- Is the timing of the bombing of the bridge a strategic move by the Ukrainians to cut off supplies for a week to coincide with some new major offensive military action?
One of the things that has been very noticeable in the last week is that the Russians have reverted to a "taking out infrastructure phase" as a way of compensating for the inability of their troops to do the deed. I have not followed all of it but they took out a dam, they took out a power station, etc. It peeked my interest a bit because a Russian born former CIA analyst just said that the taking out the infrastructure phase was part of the "Russian playbook" which squared with what I was thinking last week.
Anyway, that is a lead-up to saying, that the Kersh Bridge might be Ukraine's way of letting them know that they can move into that phase as well.
Don't know. The Ukrainians could have just gotten lucky and a Russian saboteur took care of it independently. On the other hand, this talk as though there is what Ukraine did and then there is what local resistance or "the Russians" did are somehow unrelated is absurd. Ukraine and the CIA are up to their arses in working with Russian resistance.
