Please, it's not enslavment - it's freedom and democracy.
The citizens of special reagon just don't know all the beneficial side of freedom and democracy yet.
Good thing they have Japan to introduce them to some.
Seriously now, even if colonization is seen as wrong today it actually brought as much good as it did bad.
And with 21 century mindset and tech the special region can be colonized without all the bad things that empires od old did back in the day.
