Our current missile defense technology is not effective and therefor a waste of money.

Bush and his cronies are antagonizing the Russians for no better reason than to drive up the price of energy.

Certainly building missile bases in former Soviet satellites has no value in protecting United States soil.

Certainly the opportunity cost of the billions spent is huge. We could be building infrastructure or enhancing homeland security.

Given the retaliatory capability of the US and difficulty of building an accurate ICMB without a full fledged space program the odds of serious damage to you or anyone else from such and attack is infitesmal.

You usually make more rational decisions. Could it be that your interests are more personal? Do you some way personally benfit from the manufacture of such weapons.
