The Rothschild's focus on Banks/Finance, The Rockefellers focus on Business. The Soros focus on Destabilization.
Destabilization is a business for The Soros. While the CIA destabilizes governments for the US government, The Soros destabilizes countries/regions for other Globalists.(Which means if you bring The Soros down, you bring those Globalists down).
Color Revolutions/Coups/Civil Wars are all tactics The Soros use. Funding hundreds of protest networks, using PMC/Black Op's forces to cause fighting between countries & creating feelings of unrest are just the norm for The Soros depending on the operation.
George Soros needs no introduction at this point, Its his whole family(Not just Alex) that needs more spotlight.
Alex Soros is been groomed to take over Georges operation. He's been quite active in the US operations going all the way back to BLM, even being on the ground in the Protests(He blends in with the other Numales/Beta's) helping with organization/supervision directly. (Alex also has a personal hatred of Milo, which is why he was at Berkeley helping the other protest/riot organizers & why some Soros money/connections were involved in the smear campaign against Milo).
Now The Soros aren't the only group that does destabilization, but they are the largest. Which means that if they were removed it would create a power vacuum that would reveal many different forces and individuals.
