It's not practical to build a concrete box... by what measure? Skilled labor or expense? It seems far more costly to me to lose your nuclear triad than to build concrete shelters.
They know Putin is a moderate and will not do anything. The retaliation could be just another symbolic attack to maintain the appearance of damage control and the pace of the war.Absolutely reckless idiocy to hit a strategic bomber base so far from Ukraine, it’s like they are begging to Putin to actually drop a nuke on them.
The Russians have this project that was presented to Belousov I think last weekYeah.. Guam, Kadena, Osan etc. It's unfortunately just not practical i think to build hardened shelter for something as big as strategic bombers. China did one for H-6 but doesnt seem to expand on more construction of such.
