Actually, the maneuvring speed is the max speed at which full deflection
of the controls is still allowed and it is completely unrelated to gusts.
What you both mean is the max speed for tubulent air.

Yes. I didn't see any point in further confusing the poster to whom I
replied by trying to address the terminology issue at the same time. He
clearly had a specific speed in mind that was related to gusts, but that
speed does not guarantee airframe integrity under all possible conditions.

The answer to why an airplane can be torn apart by a gust even when flying
below the allowed speed for turbulent air is simple: When the gusts are
strong enough, they will just "gust" you above that speed.

That "answer" is also incomplete. The airframe can be damaged without the
relative wind rising above the relevant certificated maximum speeds.
