In fact, based on the initial footage from Wuhan, countries should have adopted more stringent protocols when they repatriated their nationals, i.e. quarantine on arrival etc... If in doubt throw everything including the kitchen sink at just to be sure. But it is what it is. I just hope we've learnt from this and are prepared for the next one.
The 1977 H1N1 spread was never truly explained, here a possible lab incident in Russia was one of the possibilities:

The Coronavirus from Wuhan, China has a similar story, only this time it is in China.

To me a solid scientific explanation is still useful, e.g. the intimate study of the Wuhan lab into Coronavirus seems risky at best.
Yes it matters. If China (and other orgs) are responsible they should be held criminally and civilly liable. Millions have died on account of what appears to have been reckless and dangerous gain of function research. If there's no accountability, it will happen again.
There was a lot of wishful thinking and denialism back in January/February 2020.
The only country that got the initial response right was North Korea, they shut all their borders, and were mocked for it too.
The disease was already in curculation in Europe and the US when we found out about it.
Its outcome will change the way we travel for years to come just like 9/11 has.
Also, something definitely seems to have gone seriously wrong with Italy's response - they were detecting zero cases up until way too soon before their hospitals collapsed, which suggests they were doing a worse job of testing people hospitalized with potential Covid symptoms than even the US which had screwed up so badly it had an official policy of not doing so due to test shortages. Trouble is, Italy is currently run by the kind of technocrats the media likes, so there was no incentive to drag them through the mud. Instead the press spun other countries as worse because they weren't caught by surprise like Italy and so should've done better, without asking questions about how that surprise happened exactly.
Overall the idea the hospitals collapsed seems to have been a form of telephone game exaggeration, egged on by media reports claiming there were so many bodies they were piling up (actuality: undertakers were refusing to touch bodies because they are mostly old and had been told it would kill them).
What did collapse were care homes. But not because of COVID. Staff fled in fear, often back home to Eastern Europe before the borders closed, leaving too many elderly to die of dehydration and abandonment.
