Between WW1 and WW2, cartels run by the British started to become more frequent and start issues throughout Europe. They helped put Hitler into power, run Auschwitz and other concentration camps, and took over factories.
These cartels created the European Union which, as said by President Trump, was against the interests of the United States. The creators of these cartels also advocated for a system of central banks, which would put power back into the hands of these cartels later down the line.
