Let's not be silly here. European tornadoes are not taking apart houses to the foundations. Ripping off roofs or flipping over cars or even when trees are falling on a tourist tent and killing them in process has nothing to do with how houses are built in USA and nowadays even in UK and elsewhere.

I think the implication is that this is due to differing building codes. Europe builds houses with brick and concrete, that aren't so easily torn apart. That the difference is in housing quality, not in the weather.

Frankly, I think it's about half to both factors.
