Very unlikely no deaths, near impossible, almost certain a lot less would have died though. The US is down there with Brazil in how abysmal the infection and death rates are.
No excuse for that in a country that wealthy, with that much health care infrastructure and resources. Trump makes all sorts of excuses, but the facts lay it at his feet. Claimed it would go away, claimed it was a hoax, recommended demon semen afficianado's treatment regimens, lies outright about the abysmal numbers, recommends opening up when it was idiotic to do so, ignores experts in lieu of bleach injections and putting lights up your rectum. The man is a fucking imbecile.
All the other developed nations are made up of diverse states/provinces/regions what have you. Right, left and center politics, obviously likely not as partisan. The only difference is a federal government that is grossly incompetent and a political party that deals in conspiracy theories and propaganda.
It's flat Earther level of insanity to believe the US' handling of Covid has been anything but atrocious. Americans are being treated like pariahs, can't travel anywhere, you would not expect that. Result of pathetically bad leadership. A moron who takes victory laps while he does nothing.
