This is coolbert:
The last time I had heard of something like this was about thirty-five years ago. Back when in the Carter Administration the Soviet at that time attempting to flex their muscles merely to see what the response would be the motivation as reported at the time.
NOW the Iranian is doing the same? Thanks to Ynet.
"Report: Iran 'blinded' CIA spy satellite"
"European intelligence source claims Iran stuns West by 'aiming a laser burst quite accurately' at US satellite in never before reported incident. US official: If Russians provided Iran with sophisticated jamming equipment it means a lot else is at risk too"
At the time  it was described as powerful laser beams "blinding" those American satellites the purpose of which was to detect the launch of long-range missiles. The earliest warning possible, a MIDAS type satellite or similar and generally considered to be absolutely vital!
Carter also supposedly warning the Soviet NOT to repeat such a stunt, another incident would have considered to have been AN ACT OF WAR!! Further repetitions not observed, at least until NOW?
