>The UK chief scientist, Patrick Vallance, has stated that they suspect a winter resurgence is possible, thus I also question the value of waiting and flattening curves.

By winter we'd have more equipment, masks, drugs tested, doctors taking a break, etc. The big spread also stops in warmer climate.

>World governments should clarify this matter by saying that a bad winter resurgence, months after nations are fatigued with lockdown, is definitely not going to happen.

Of course it's possible and very likely to happen. The answer is not no lockdown, it's a second lockdown then as the need arises.
