What really will happen is that our trade partners will drop or significantly lower THEIR tariffs on our goods, and we will either drop or lower the proposed tariffs on their goods.
In any event, it will be an improvement from our standpoint, which is all that matters in these issues.
The tariffs were never meant to bring any revenue into the US treasury, but as a negotiating ploy to reduce the artificial non-tariff barriers to open and fair trade between two nations to their mutual benefit.
The non-tariff barriers include refusal to accept the proposed trade goods unless those goods met legal requirements often much higher than that accepted by the US markets, like for instance different varieties of cheese or wine, as some national entities can get very snobbish about the virtues of their own domestic production, and even a small misinterpretation is basis for total embargo on whole classes of goods.
