If Every American died from Covid-19 would World Peace be achieved?

No, wars would break out all over the world as regional aggressors would no longer have anybody to stand against them.

China would attack Taiwan, North Korea would attack South Korea, Russia would resume the conquest of Ukraine, Iran (thanks to Russian and Chinese weapons) would try to be hegemon of the Persian Gulf, Turkey would commence their war/genocide of the Kurds, etc.

Millions would die directly, and then indirectly from the disruption of economies and supply chains.

your priorities will likely change fairly soon........

H*ll no.  Only if every Democrat died.  Americans are not the ones causing chaos.  It's the democrats who want the one world order and they want it now and are fighting and destroying history in order to get it.

No. I'm afraid not. There are Americas all over the world.

No. Because evil, greed, and hatred is a heart disorder not a skin disorder. Americans are not the only ones in the world afflicted with the disorder.

People do not hate america, they hate each other.  I wish you the best as your neighbors hate and kill you.  It's gonna happen.

No, but there would be an improvement if one large orange turd was to die from it.

Of course not ,Various sects  of people would fight each other

                                     NO

I don't think so, because

I'm not sure, but I think there are wars in the world that America is not involved in

.I'll check, and get back to you.
