As we mentioned in the September “Economic and Fiscal Outlook”, one of the major areas of spending, around which we weren't in a good position to provide an estimate, was the government's commitment to the 5% NATO commitment, and we were focused on 2%. Concerning the difference between 2% and 5%, we continue to not have enough detail at this point.
At this juncture, it's unclear how much of the additional spending will overlap with other areas of spending, but suffice it to say that I think, going back to the testimony that I offered at the government operations committee, it would be tens of billions of dollars of additional spending.
