It was thru trial and error that American inteeligence is more probably more astute in dealing with foreign intelligence networks, a process learned thru its long confrontation with the KGB.
The subsequent testimony of Mc Cloy claiming that the order was based on assesments of MAGIC intercepts are just that . He probably was trying to justify his actions regarding Japanese - American internment during that period.
