In my understanding Trump is not evil, but there are some countries that want to attack Trump's president, because they do not dare to weapons, they use their weapons economy, as is happening now.
But Trump's president policy on tariffs, not his will, but because of those who want to bring down the US dollar and economy so Trump replied with a high tariff policy, meaning that with the world high tariff policy could see the US Having the power to control the world economy, I think it is Trump's President's trick to repel the enemy, proven new US president policy in implementing the world has been chaotic like leeches in the sun in the sun under the hot sun.
