In short, Sen. Levin and other longtime opponents of missile defense plan to use “testing” - set to an unrealistically high level - to stop missile defense.

Imagine this: The year is 45 BC, and Senator Levinus argues against the Roman short sword until it is 'tested'.

These people are insane.

If you take a look at weapons development (say in the last 100 years) you find it's much better to have a 90% effective weapon and the will to use it, than to wait for perfection. Unreasonable demands are being made when we should be fielding weapons systems, getting experience and fixing problems.
