why the US put all the exporting countries in the US market on the list of sanct

I just read an article:

The question that I always wonder is why during the tenure of President D. Trump, the US always put the exporting countries in the US market on the list of sanctions by some form. Can those things really make America great again?

The idea of adding sanctions to countries that export to US trade markets is a way to ensure the other traders have an inherent disadvantage. Whether it works or not is another question.

Some trade sanctions were placed to ensure home grown innovation and production can thrive though ensuring a higher demand for working class and middle class workers (low skilled, skilled and highly skilled staff).

If you can buy something from a company in the US for $6 that Europe sells for $5 including delivery but is then slapped with a 100% tariff, you'd probably stick with the $6 one.

The reason I say some of them may not have worked would be with things like high tariffs on aeroplanes, which could take stock away from the US and mean more planes are registered in Europe., the UAE, Canada etc.
