China won the trade war.
Its mixed economy composed of both state capitalism and free enterprise can process raw materials more efficiently that any other industrialised nation.
This has come to the point of being an existential threat to the petrodollar as US debt closes in on $40 Trillion and Chinas annual trade surplus surpasses $1 Trillion.
China has become the major buyer of oil exporting nations which were foundational to USD/Petrodollar hegemony.
So Trump is responding like a typical poor loser imperialist bully and attacking Chinas energy suppliers- especially those who accept payment in Yuan.
The wealth and power of USA is built upon the petrodollar hegemony which is in turn dependent upon US military power projection capacity.
Iran has demonstrated that an asymmetric response to the declining effectiveness of the US military can result in stalemate and exposes the USA as a declining and ineffective 'security' partner.
How much Trump has to pay for plastic toys is the least of his concerns- he is revealing how unreliable and ineffective US military power projection has become.
It cannot build anymore of its high tech military equipment without the rare earths China now refuses to sell.
He has 2 days left before the US Congress need to grant him an extension of power to continue his unlawful trade embargo and invasion of Iran.
USA has run out of Interceptors and risks having its antiquated aircraft carriers blasted to the bottom of the sea by Iranian missiles.
The world is watching and the clock is ticking upon declining US empires petrodollar wealth and hegemony.
USA is losing in its desperate and unlawful attempts to block free trade and preserve the petrodollar via war crimes.
