Didn’t Trump want lower FED rates? Why did he started this war then?

I mean, he was scorning Powell because the rates weren't going down fast enough. He now had a new chairman to do so from June onwards.

The US debt isn't financeable with rates above the current. A 5% rate is too much, long-term. This war will inevitably trigger rate increases this year. So, it is exactly the opposite of what Trump wanted.

Isn't that controversial? Am I missing something?
