When they show up with metal detectors looking for buried guns, the shooting war will have already begun.
BTW, when the USSR fell in 1991, buried PPSh burp guns began springing up like mushrooms after a rain.
“Why did Poles pour motor oil on their flower gardens? So their guns wouldn’t rust!”
I have read,, many years ago, that the Commie Russians stashed several caches of weapons INSIDE the US for their agents to use, if a war ever broke out.
To my knowledge none of these caches have turned up.
