The Ukrainians are happy as this is a public and significant impact to the Russian war effort. At a minimum, bridge vehicle traffic throughput is reduced by 50%, there are unknown, but probable impacts to rail traffic.
Russia has clear logistical problems that limit their operational reach. This make those worse. So yes, the Ukrainians have plenty to be happy about.
As stated prior you’d think Ukraine military just took Moscow by A blast at A bridge.....so as usual Ukraine propaganda machinery always over estimates every battle or attack as favorabe to them in order to keep their militray soldiers in the fight and the public in check............Yet any map on land territory clearly remains that Russia’ has gained most all of their eastern landbridge they have sought. .....how much of that they will determine is necessary to secure their border areas and ports etc. is still undetermined..... Either or this conflict will not end until negotiated.
