An import tariff would be a good start.
I remember Trump placing tariffs on Chinese goods, but the media assured us it was done only because Trump was a racist.
I also remember Trump warning the NATO countries of Russia and China’s desire to expand their borders. He also demanded the NATO countries help pay for the US protection of their countries and the need to start producing weapons.
Finally, Trump warned the EU about doing business with Russia.
This:
“An import tariff would be a good start.”
