Ukraine Is Building An Underground City Along The Front Lines

A wood burner with pipe going to outside? Wouldn't that alert people to where you are? Bunker busters can't blow those open? This just doesn't look believable as protection but would be nice to rest.... Tunnels have been used for thousands of years..... I want this war to end with no more dying, no more destruction. USA can quit pushing so hard to control everything and everyone! Paranoia creates problems!
