I believe this is the kind of strategy that Trump supporters believe it works. The global economy is an interconnected fabric of intertwined economies, and if one collapses, a domino effect is inevitable. This is similar to the human body: when one organ becomes ill, the entire body is affected, becoming afflicted with fever and disease. The United States itself is currently the most affected by US sanctions, and don't expect this to improve in the long term. If access to US markets continues to be difficult, partners will seek and find new markets, while there is a strong possibility that the US will fail to find new partners, especially given the presence of a strong competitor like China.
in this case Trump supporters will be very confident in the decision taken to keep the US economy in power, and that makes them make decisions without seeing the many shortcomings that will occur among themselves, and China is a strong competitor who takes immediate action, of course that is an obstacle for the US which they think will soften, with high tariffs, of course the global economic sector becomes sluggish.
What Trump is doing is like playing with fire: either he survives and everyone else gets burned, or they all get burned. Trump never talks about his country losing global partners entrusted with providing the American economy with what it needs to achieve growth. All we see today is Trump making gains through political blackmail, but these gains are limited and incapable of achieving sustainable progress. His success in establishing good relations with Russia has not yielded any economic gains other than halting the war expenditures it was sending to Ukraine, and even the precious metals agreement with Ukraine was unsuccessful, literally failing to achieve any ambitious goal. Likewise, his rapprochement with the oil-rich Gulf states will yield good gains in terms of investments, but this cannot compensate for the losses caused by the tariff war on the American economy, which has lost its two most important economic partners, Canada and Mexico.
