And the third side of it was that Ukraine technically could have prevented opening this front overall by shooting up the staging areas and logistical support of it, but "line on map" retarded restrictions prevent it to this day.Seems like Ukraine political corruption didn't magically disappear on February 24, 2022 and the millions of dollars given to Kharkhiv's corruptocrats to build defenses instead went to the laundromat, hence why the Russians just walked over the border.
Ukrainian Corruption Center reports northern border defense funds were diverted to fake companies, letting Russians walk right across border in new Kharkiv offensive
It has been reported that the Russian military was able to walk into northern Ukraine due to defense systems missing this past week.humanevents.com
Of course on the flipside the Kremlin squandered an opportunity to possibly REALLY change the course of the war from slowly taking territory in an enormously costly manner to instead being in field artillery range of Kharkhiv and thus forcing some major issues.
This sort of shit makes it more easier to fight Russian forces when they have some "tail" on Ukrainian territory, so that it can be hit properly.
Holding on to a defensive right on the border while the other side could have fire and logistical support from Russian territory where it can't be hit with Ukraine's best weapons is... suboptimal.
