The Guardian is reporting that recent documents have revealed that the US is looking towards the using orbital platforms for weapons, and researching the use of weapons in space:
Internal USAF documents reveal that seizing control of the ‘final frontier’ is deemed essential for modern warfare. Counterspace Operations reveals that destroying enemy satellites would improve the chance of victory. It states: ‘Space superiority provides freedom to attack as well as freedom from attack. Space and air superiority are crucial first steps in any military operation.’
Theresa Hitchens, vice-president of a Washington-based independent think-tank, the Centre for Defence Information, said: ‘These documents show that they are taking space control seriously.’
Inevitable I suppose.
