Completely non political. But would love to hear people’s thoughts on why / or if the US appears to be deliberately tanking the market?

As I said, this is non political, purely objective UK person looking in to what is going on with the tariffs and the market. No disrespect to any political points of view. I’m just researching and trying to make sense of what is motivating certain moves that are clearly having at least temporarily a very bad effect on the market. The last time such massive tariffs were introduced in order to strengthen the US economy and its manufacturing was the catalyst to the Great Depression in the 1930’s. It seems unlikely IMO that anyone making those decisions would be unaware of that, so what do you think the reasons might be? Is it deliberate to say bring interest rates down, or just a misguided idea, or or? 🤷‍♂️ Would love to hear people’s opinions on this.
