"If WTO is so sacred that it is more important than national interest than VAT can be used to substitute for the tariffs (other countries use VAT for this purpose)."
So you support adding a VAT to our other taxes? That is politically a non-starter. Mnay conservatives are highly skeptical of giving the federal government another way of taxing us, in addition to the tax forms already in existence.
I see only two options to prevent the collapse of American industry - restauration of the tariffs or VAT (which can be used like tariffs). I prefer the first.
