U.S. deployment of space weapons will let the "genie out of the bottle"
It is important to understand that there is another, more likely "inevitability" involved if the United States pursues these capabilities, that is: other nations almost assuredly would, too. Although Russia and China have declared a moratorium on ASAT testing, it would be irresponsible for either state not to acquire their own deterrent to potential U.S. ASAT attacks.
Russian and Chinese ASATs may, in turn, be a reason (or, perhaps, just an excuse) for states such as India to follow suit. Still other countries -- and this includes North Korea and probably Iran -- that have the desire, but not yet the skills, would then be able to "draft" in the wake of the big powers through espionage, declassification and, perhaps, the black market. The point is this: once the United States has gone down the ASAT road, there likely won't be an option of negotiating a ban on ASATs or discouraging the proliferation of legitimate dual-use technologies such as microsatellites. As we have learned with nuclear and missile proliferation, once the genie is out of the bottle, it is out for good.
