Hey Bro! It's not a matter of being scared but rather prepared. Shooting down satellites is not that easy and if you think we can do it at will you are sadly mistaken. The satellite China shot down was so rigged in their favor that a situation similar in real life is extremely unlikely. Space based weapons are our only real means effectively of targeting objects in space. As for Iran... http://www.defensetech.org/archives/004673.html It seems the type of launch Iran just demonstrated is idea for delivering EMPs.

Iran puts a satellite in orbit... We take ourselves out of the space based weapons party? Makes sense to me. HopeNChange will get us through the day!
