Then it might be possible to see if gun control would really be

And since
the people decided, the US still has few restrictions for gun

In Europe, democracy arrived later. Meanwhile, European

when
democracy arrived in Europe, people were already used to metric
units, and also to live without guns.

You lost some space probes due to conversion errors between metric
and US units.

It was really a "cultural" error, much more so than conversion.

The more often such conversion must be made, the more
likely those occasional conversion errors will be.

Which is one reason why English units are provided on most consumer products. Metric is not particularly helpful in most such cases.
