The first thing is to learn what not to do. What we've seen happening with U.S. sanctions in the past 10 years or so is a consequence of overcompliance in financial sector de-risking. That has very broad-ranging ramifications that go way beyond the intended functions of sanctions. The first lesson is to find a very delicate balance between compliance—that means ensuring correct compliance—and not falling onto the other side of the scale, which would be overcompliance.
Again, I come back to the point that OFAC depends on hundreds of people. That extends to other government agencies, as well. There's an extremely close working relationship, as I understand it, between different government departments within the U.S.
That, again, is a key issue: working together with others that play different roles. We see how that's not always the case when the decision-making, or at least the responsibility for enforcing sanctions, falls to one particular part of government. It's vital to work across the board, as well.
