breakthrough / mishandle

[vil]

Dear teachers,

Would you be kind enough to tell me whether I am right with my interpretation of the terms in bold in the following sentence?

Before our eyes, the tax reform, which could have produced a real breakthrough,has been mishandled.

breakthrough = a major achievement or success that permits further progress, as in technology

mishandle = to deal with clumsily or inefficiently; mismanage

Thanks for your efforts.

Regards,

V.

As far as I'm concerned, the tax reform itself could be a breaktrough instead of producing it. But other than that the sentence looked fine to me.
