Tariffs are a big deal even if they don't lead to geopolitical conflict. The only way that spending adjusts when tariffs are imposed is that consumer wealth is destroyed as they either have to pay higher prices or forgo satisfying their needs and wants. Either outcome is not good.
What do you mean by the "supply chain I will be realigned"?
This is my take on what is happening. Trump wants globalists to establish an alternative source from other countries. For example, Apple should manufacture iPhones in Mexico or Thailand. The same reason as to why Trump wants to impose tariffs on uranium imports which currently comes from russia and kazhaistan. To reduce risk of disruptIon on the global supply chain in the event of a geopolitical event.
