To understand Trump's various unreliable behaviors, one must deeply understand a series of his goals:

1. The depreciation of the dollar is beneficial for exports.

2. Allies purchase more U.S. Treasury bonds and lower yields.

3. OPEC increases production to lower inflation and interest rates.

4. U.S. stocks will fall first and then rise, with the rise lasting until the midterm elections at the end of the year to gain high voter sentiment.

5. All countries except China accept U.S. conditions on tariffs and form a trade blockade against China.

6. Increase the U.S. debt ceiling to reduce taxes.

7. Low corporate tax rates attract or compel core manufacturing to return, including steel, automobiles, chips, and rare earths.

8. All U.S. businesses use stablecoins to lock in the liquidity of U.S. Treasury bonds.

9. Significantly reduce the size of the government and cut waste in the welfare system to greatly decrease the scale of the government deficit.

10. Military spending shifts to outer space to achieve the best military deterrent effect.

One must admit that if this series of goals is achieved, the U.S. will maintain its absolute first position in global comprehensive strength for the next few decades, though the difficulty is not small.

So in the face of Grandpa Trump's unconventional style, the best response is to understand his actions from the reverse of his strategic goals.
