I did NOT claim that bypassing the tariffs will be easy.
Tariffs reduction will be doable, but not easy.

> tariffs will have significant negative impact

Correct. Tariffs will have a significant negative impact.
Even 1% decline in profitability is quite significant.
However this significant negative impact is not going to be disastrous.
