I can't believe I only learned about this this development today:
Was there none of the usual noise from the pundits just because in space, nobody can hear you scream? Anyway the news is breathtaking. Especially if you happen to be a little more familiar than the current president with the anti-militarizing "Outer Space Treaty" the United States signed in 1967, or with the 1962 "Declaration of Principles" the U.N. adopted in 1962, or even just with the spirit of space law for the last half century or so.
"The United States considers space capabilities — including the ground and space segments and supporting links — vital to its national interests," the policy said.
"Consistent with this policy, the United States will: preserve its rights, capabilities, and freedom of action in space; dissuade or deter others from either impeding those rights or developing capabilities intended to do so; take those actions necessary to protect its space capabilities; respond to interference; and deny...the use of space capabilities hostile to U.S. national interests.". . . .
"The United States will oppose the development of new legal regimes or other restrictions that seek to prohibit or limit U.S. access to or use of space."
Right, well anyway, just remember: Nobody leave Earth or enter orbit without permission from the United States. We just say so.
