When you say "devastate entire industries",which does this imply?

A:devastate some of the industries in the nation completely.

B:devastate all industries in the nation

This is a quote from President Trump's tweet.
Some people are wondering the meaning of "entire".
They think it implies destroying "certain" sectors of industries "completely".
My opinion is that "entire" just means "whole",
so the sentence means:destroy all industries in the nation.
Which is right?
