As opposed to slaughtering or enslaving the inhabitants of an existing island then claiming territorial rights, like in the good old days?
At least in the good old days it was a hard fought battle that our glorious troops and superb commanders won against well equipped and blood thirsty naked nasty types , delivered to the distant shores by a Navy that was the envy of every land locked country in the World. The World I say.
Which we then, by the grace of our Divine Providence, bought piece and prosperity to those savage races who simply had no concept of bagging a brace of the local wildlife before tea and cucumber sandwiches at mid afternoon, followed by a bit of a siesta before a decent round of 'shag the local totty' while we watched the sun never go down with a large G&T in hand. Lords and Masters of all we surveyed.
Ah, I miss the good old days
