"The International Security Advisory Board (ISAB) welcomes and supports the National Security Presidential Directive (NSPD) of August 31, 2006, 'U.S. National Space Policy,' and its articulation of the importance of space to U.S. national security, economic well-being, and technological advancement. While the broad outlines and the specifics of the current policy do not differ significantly from the 1996 National Space Policy, the new national space policy is an important public document that articulates key points in an unclassified summary. It should be used as the basis for national and international dialogue on the importance of space. The ISAB also wishes to note that the bipartisan Rumsfeld Commission report (Report of the Commission to Assess United States National Security Space Management and Organization), issued on January 11, 2001, is a useful and logical companion to the U.S. National Space Policy directive. It set forth important recommendations to implement the policy described by that directive. It also emphasized that space can become a real national priority only through strong and continuing leadership from the highest levels of the U.S. Government. The United States does not seek to deny other nations' access to and use of space for peaceful purposes. It only seeks to preserve its own free access to and use of space for peaceful purposes. The document does reaffirm, however, that space is of such critical importance to the United States, commercially and militarily, that it is a vital national interest; and it does recognize that space is an arena of growing competition and challenge, as well as opportunity."
