This might make Trump happy, but more importantly it makes the military happy. No military leader with any intelligence is happy with so much critical for war supply chain being in China or Taiwan - the two are showing signs of going to war with each other in the future. (it may not happen, but there are enough signs military and political leaders should worry). Military leaders are not just the US, leaders in Europe are happy too - they may not trust the US but the US is still at least a second option (and Trump is 79: he is statistically unlikely to live much longer)
