Yes, it became part of the standard in rev 2. 3DES will be completely forbidden for federal use after the end of the year. Sweet32 was a demo, attacks get better. And there are other generic attacks against overuse of 64-bit blockciphers. Outside of a few usecases in constrained environments there’s no good reason to use a 64-bit blockcipher anymore (and there are better choices than DES/IDEA for those cases).
Just to be clear, you are asking how all this evidence refutes your totally unsupported assertion that 3DES is “perfectly secure” against the NSA? When even the NSA, who co-designed DES in the first place, forbid its continued use?
