The rules based order was concocted by the USA immediately post WW2: The UN The IMF The World Bank The USD Global Reserve Status etc etc etc.
In practice, however, the principle of "No country can bolster its National Security at the expense of another; particularly if that "another" is a Nuke Power Neighbour.
My post above challenges that principle...ie: That if its OK or the Ukraine to bolster its national Security by joining NATO then why is it not OK for say Cuba or Venezuela to join the SCO and have Chinese/Russian WMDs based in their respective countries for national security purposes ?
The principles that apply to the Ukraine joining NATO in this instance, apply to Cuba and Venezuela joining the SCO (Shanghai Cooperation Organisation)
(source Wikipedia)
IMO the SCO + BRI + BRICS will eventually challenge the US Rules Based Order and with it the role of the USA as being the global policeman and the role of the USD as the Global Reserve Currency.
This Ukrainian War has to be looked at in this context and it has simply accelerated the process so while the Ukrainian war was a win for expanding NATO membership, it also accelerated the China led SCO, BRICS, SCO development and with it the formation of an international trading system excluding the USD and related institutions.(eg SWIFT etc)
