Do you think there can be something very productive as an outcome of these 90 days buffer time for the resolution of other issues beyond TARRIFS?

The loss of western productive capacity that has occurs due to the financialization that took hold for the 1980s onwards would be extremely difficult if not impossible to reverse. The west/USA is now entirely dependent upon its legacy hegemony over banking and financial markets.

The trade war has already been won by China and the process of China gaining control of the tertiary level protocols and institutions has begun. Trump and whoever follows him can and probably will seek to preserve as much of US wealth and power as he can. 'Crypto' is the modern vehicle by which some of that process could be managed just as the British managed their decline via multiple offshore tax havens.

However it will be more difficult for US wealth to be preserved in a similar manner as China is much less aligned to US interests than Britain was, and remains. USA can probably remain a regional power, perhaps, at best, from Greenland south to cover the entire Americas. The end of US exceptionalism is however looking to be the reality.
