So has genocide...
> there was no formal declaration or ability for them to fight back
The last formally declared war by the US was WWII, and the second Iraq war was absurdly asymmetrical, they effectively had no "ability for them to fight back", we murdered countless civilians. And go ahead and try to find actual numbers regarding those deaths. There are wide discrepancies between US official numbers, US approved media numbers and numbers from other watch groups. If you think our use of force in the middle east is anything like 'officially declared war between nations' you need to spend more time researching.
That's just Iraq, there's a plenty of campaigns right now all through out the middle east. And let's not forget the massive funding of Israel and their perpetual work to drive the Palestinians from their homes. Read up on that and tell me that's not genocide. But if you critique that publicly you'll face immense political backlash.
And don't get me started on the way our governments still actively work to destabilize first nations communities and cultures in the US. We unquestionably committed genocide against native populations in our history as a country but you're naive if you think we still aren't working to actively destroy what culture remains (Canada is equally if not no more so guilty of this).
> and it’s happening largely in secret
The US and China have very different forms of propaganda, but the fact that you think that the US is largely innocent of crimes like these should give anyone reading a sense of how powerful US propaganda and media control really is.
