As far as I know, not even the infamous dictators of the 20th century bombed their own populations.
It’s the kind of thing only a total retard would threaten.
FWIW and respecfully, Mao, Stalin, Hitler, Pol Pot, and many others killed huge numbers of their own citizens that they viewed as threatening their power (or simply inconvenient).
The first two killed far more than both “world wars” in the last century.
This is very dangerous rhetoric.
Tyrants who order live fire massacres of their own populations usually end up like Ceaucescu.
