As an American, I completely agree with this.
You do have power. Trump messed up international trade by raising tariffs on China. That cost food and supplies for every country to increase because we are all connected through trade. If China has to pay more to export, then it raises prices and tariffs to every country it deals with. Those countries then have to raise prices and increase tariffs to other countries to pay for what they need to import. It's a vicious circle and the people pay for it. You can start being vocal to your Ministers, your news outlets, and social media letting them know you will not tolerate another Trump global fiasco. Those officials will start voicing concerns--they have more push if they are speaking for their people. If US industry feel like Trump is threatening commerce even just running for office, they will push on the GOP legislators and not fund Trump. You have power--use it. Speak up. Organize petitions, write letters... rally the people. We need all the help we can get. Think about this too--it seems the bad leaders are being bold just at the idea that Trump might come back into power. They know he will call them great people and back them. Putin wants his puppet back so funding to Ukraine will stop and the Middle East is having a mean boy frat party. You think that is bad now, if Trump is in office, the Middle East will burn as surrounding countries take sides. Then it will be too late to put that genie back in the bottle. Everyone will suffer. Refugee influx will increase, prices will sky rocket, and acts of terrorism will increase. What happens in one place impacts us all--they are all connected. Speak up.
