While I agree with the theory, this is another non-solution that has already proven not to work because politicians in all countries like protectionism. It keeps them in power.
Please share how you have determined to drive all the world's politicians (and dictators and looters) out of positions of political power and manipulation?

How about a real solution for the real world? Maybe Trump would like to hear that solution, too.

The solution is to have unregulated trade, no trade barriers, even if other nations enact them on their side. As lucky pointed out, we have been through this recently in a Free Trade discussion started by coaldigger. At some level, arguing is pointless, and that is the reason why it remains important to at least state your case.

The reasons and facts in favor of unilateral free trade are easy to find at http://fee.org and the Online Library of Liberty.

Those are the same as they were 150 years ago when advocates of free trade argued against tariffs that supported steel mills and coal mines.

This is yet another example of why so-called "conservatives" are not principled advocates of individual rights.

Many conservatives were attracted by the Atlas Shrugged movies without exploring the deeper philosophy behind what was essentially a love story. In the book, when John Galt is captured, and being held at the Wayne-Falkland, he has a tet-a-tet with Mr. Thompson, the head of state. It is the same discussion we are having here.

What's your solution?

Two points:
1- That tariffs are bad, eg pull gets exemptions.
We had a go at this in a recent post-
Free Trade, 9 days ago, by coaldigger

2- That Trump supporters are silent when Trump brings in tariffs.
True unfortunately for some.
In the above, many Trump supporters (my guess at who they support) gave some
excuses/rationalizations-
that he did not think it thru, he cannot think, he is impulsive,
he thinks it is an opening gambit to a good negotiated outcome.

There is the strong argument that, for those who want smaller government, there
is no need to think it thru, that the action is a use of powers government should
not have.

There are so many conservatives on this site for whom the argument-
it is bad in itself - is insufficient, so a few more government employees is
ok if the intentions are good.
For those, note, it does not end there. Many are hurt by tariffs who cannot get
an exemption, so sooner or later there are subsidies and buying preferences to
compensate. All this needs rules to be written and supervised, there is job
growth in regulatory agencies, tribunals and the courts.
New jobs- yes, economic growth- no.
