Opinions on the REASONS behind the spraying vary, but consensus seems to be our govts are dumping junk on us in order to destroy our immune systems. Then, a really bad strain of weaponized flu, or a toxic vaccine would have devestating effects (makes you wonder why the vaccine makers wanted to be excused from legal liability in the Homeland Security Act).

There is one thing I always wonder about when I hear all these conspiracy theories:
What do they have to gain by doing this? If nobody has anything to gain, then the alleged action doesn't make much sense - and then I suspect that the allegations are untrue.
The U.S. Government has little to gain by preying on its own citizens and allies.
