FAIL.
The words 'impenetrable dome' have quotation marks around them for a reason. They are to indicate an actual physical dome is not meant.
Ever hear of Israel's 'Iron Dome' (notice the marks around 'Iron Dome')?
It's an air defense system, not an actual, tangible, physical, impenetrable dome, either.
Try again.
It actually says that in the article the moron posted.
