This is the Congressional Budget Office (CBO) Cost Estimate as ordered reported by the Senate Committee on Foreign Relations on June 24, 2021. From the Document: "S. 2000 would authorize appropriations of $134 million over the 2022-2026 period for defense-related assistance to Greece. Using historical spending rates for those programs, CBO estimates that implementing the bill would cost a total of $62 million over that period, subject to appropriation of the specified amounts. The remainder would be spent after 2026. [...] On the basis of information about the costs to prepare similar reports, CBO estimates that satisfying those requirements would cost less than $500,000 over the 2021-2026 period."
