Forty years in a cycle, Japan has once again become America's blood bag. Looking at the details of the US-Japan trade agreement: 1) Japan establishes a $550 billion fund, with investments led by the US, and the US takes 90% of the profits; 2) Tariffs are reduced to 15%, but will be reviewed by the US every 12 months. If Japan does not meet its commitments, the rate will revert to 25%; 3) Opening up to US rice imports, purchasing $8 billion in US agricultural products; 4) Opening the market to US cars, industrial goods, and consumer products (Japan's most vital lifeline), committing to purchase 100 Boeing aircraft and billions of dollars in arms procurement. Looking back from 2025, what does it feel like to reflect on 1985? One must say that the conditions of today's US-Japan trade agreement are far from comparable to the Plaza Accord of that time. One can only say that from Reagan to Trump, it's a forty-year cycle. Both have just experienced historic inflation, the same Republican landslide victory in the elections, and the same intense geopolitical competition between the top two powers. Once again, the big brother is drawing blood from the little brother to replenish itself, but this time, there will be more little brothers supplying blood.
