What is the point of countries if their territory can never change?

Take them in as refugees and give the land back then.
Also: since when are they in danger?

>Russia is doing poorly
I guess that depends on what your definition of “poorly” is. They have one of the strongest militaries in the world.

>since when are they in danger?
Since America got involved in their country.

What's the actual danger?

Immigration/refugees

>and give the land back then
Why?

There is no point in countries they are a disgrace to humanity and a product of the Jews

This can be achieved in many ways. 9/10 times you only see economic domination, by investing in the poor country and controlling their political class through bribery, the locals simply cant pay as much. Still a takeover.
Its also common to see guerrilla forces take over poor parts of weak countries, nobody respects the central government.

One world government then?

>One of the strongest
They are in the top 100 militaries
