My position is that masks and 16+ vaccination were enough to achieve R<1, for Delta.zero covid was never an option. That's the part you don't want to come to terms with. Colin Powell, and others, are high risk. Something was going to eventually cause his death. Is your rationale that 100% vaccination and eradication would have averted a mutation?
Covid in this instant was a contributor, in other years another respiratory virus would have been the culprit.
Zero? No. Just low level endemic. But low level endemic is far better than 200K additional deaths.
