Critics argue Trump’s aggressive diplomacy weakens trust, while supporters claim it reinforces U.S. strength.

It might be worth to mention the concepts of soft power and hard power here. I'll oversimplify it here:

• soft power - "do what I say, it'll be better for you"
• hard power - "do what I say, otherwise I'll go against you"

The critics are focusing on the soft power, and they're IMO spot on - Trump is ruining every bit of soft power that USA has (or had), by taunting allied governments.

In the meantime, the supporters are focusing on hard power... and they're completely off-mark. Hard power depends on your economical and military capabilities, and those threats are not improving either.

"But what about the tariffs?", someone might ask. Does anyone here genuinely believe that they'll improve USA's economy?

risks? it ALREADY has

This is absolutely the case. Say what you will about China but at least it's not totally random in its decision making, self destructive, and openly hostile (it does that in secret). On all counts it's a better partner than the USA right now.

that's exactly what he wants these tariffs are retaliation for the sanctions on Russia. now the global economy is shittier
