Nothing wrong with looking at easing the lockdown, if done in the right way, where I disagree is that you think it solved nothing. Most people agree south korea, was the way to go, but that chance was squandered from the start. Your post suggests that you think we already reached herd immunity. Seen as 3 out of 4 susspected and tested cases are negative, it's virtually impossible.
It's like you're desperate to try and not be wrong about your opening post in the thread.
As stated before it's quite clear, that those countries that locked down soonest, followed a different trajectory.
