I think they'd point you to the fine print "working for". Warburg and Schiff were Jews. Zionism as a thing called Zionism started 1896/7 but the concept of a Jewish return to Zion predates England. See: American history before 1865, the Talmud.

Its because he's an racist idiot.
The fact is, the major US jewish bankers didn't really take hold until the 30s with Lehman and Goldman. They were around of course
The bankers and politicians in 1913 weren't major zionists, and certainly weren't working for Jewish overloads or whatever nonsense. They were mostly just industrialists and financiers of industry and government bonds.
Dude is a dipshit that reposted something that he clearly doesn't understand.
