It's super easy to retrospectively say "they should've done something else". You might think that even you would do the right choice, but you are wrong.
Such decision is hard for any authority. You may vote for any person in the whole world and the result would probably be similar. Lockdown delivered too early could send whole country into chaos.
Also China managed this so well that it actually could work counterproductive for other countries.
What I'm trying to say is: Don't judge others. You have little idea of the situation they are in, and saying retrospectively "you should've known better" is just childish. Just learn from their mistakes.
With your attitude, you can choose any party and will always be unhappy about the choice.
