Actually every race/country has a history of fighting for or defending land aquisitions, even Australia's indigenous amongst themselves.
There is no reason Australia should roll over and become the borderless nation like we have no standards and are here for the taking.
Such an attitude is a double standard when we are busy defining indigenous tribal borders and 'returning' land.
Perhaps we should also use the same logic and tell the indigenous folk the left say Aus is now a free for all and your tribal lands dont mean anything.
The deliberate double standard held by the left is the very reason they are not fit to govern for the people already here in this country.
