The moral equivocating is absolutely despicable.
Has the US killed children? yes! Was that ever the stated or unstated goal? Never.
I would add, contrary to that, physical eradication of certain parts of society has been and is the goal of Russian rulers. (Ukrainian hunger, Ukrainian dams in 1930s - the purge of Ukrainians didn't start February last year)
The US regime has (a) committed repeated genocides including children against Native Americans and black slaves (b) perpetuated the Jim Crow laws including terror, bombings and lynchings against the black population up through the 60s (c) invaded or directly supported lethal coups, dictators and genocides in Guatemala, Chile, Argentina, Brazil, Paraguay, Indonesia (d) overthrown governments and participated in assassination plots in South Vietnam, Congo, Iran (e) supported Saudi Arabia in their shameful war in Yemen. An incomplete list to be sure.
It's not that this is worse or better than [some other nation]. It's just that it's bad and pretending that the regime "meant well" is indefensible.
Even a drunk driver, who hits a child, is seen differently than a sober driver who purposefully decided to run one down.
Do you want to spell out what countries, specifically, you have in mind here?
That isn't to mention CIA backed coups, etc.
Isn't it weird most Americans can't name, much less find on a map, the nations they are at war with?
