"which is (as the article fails to mention but should have) similar to some European countries, so can't be too terrible."

Judging from Wikipedia (which of course is subject to correction), Norway has an ordinary 21 year maximum, but it can be increased indefinitely if they think the person is a danger to society. Some other countries, but not very many, have a 25 year maximum. Most other countries that have a maximum have 30-50 years.

None of these, not even 25 years, is reasonably similar to a 10 year maximum.
