The interesting bit is that Trump and many of his supporters seem (to me) to be openly working to bring an end to US dominance and promote the likes of China to the top spot instead. The US got its global power by being relatively undestroyed by WWII, and thus both willing and able to pay to rebuild the rest of the world, while performing some very sneaky currency and political manipulations. Now the US wants to cut off our allies and strengthen our enemies.

You have to differentiate what countries leaders know and the general population knows.

I'd argue that leaders in South/Central America were under no illusions of how the US operated - the fact that Trump does so openly doesn't really change that. The 'great game' goes on.

What's changed is the wider public perception - both home and abroad. The question is will that create political pressure for a change.

For example, the new openess of the US-Israeli agenda in Gaza and the West Bank and elsewhere appears to have really shifted the political landscape domestically in the US in terms of unconditional support for Israel. The US self image is potentially shifting - this could have much bigger domestic implications.

Likewise aboard, while the current US hostility to China is not a suprise to the leadership in China - it's a continuation. The view of the US in the general population in China will be shifting, which will potentially create political change in the response.

Now I'm not sure Trump understands he is potentially squandering that soft power, because he lives a bubble which applauds the strongman messaging - and let's face it - he has won 2 elections on the back of it.

That for me here is the real risk - people shifting from thinking they were the good guys ( even if that was not entirely true ) to accepting they are out for themselves - and how that then effects both domestic and foreign policy over time - will US society fragment with people being ever more isolated domestically and as a country abroad?
