Yes, Australia was colonized along with other newly discovered lands. We however, have tried to right some of the wrongs done over 200 years ago - heard of Native Title? To get back to this century......it is a lie to say that Egypt and Jordan attacked Israel, because they didn't, and Israel's actions were not just defensive, they used the opportunity to take vast tracts of Palestinian land and then started illegally settling that land. I do agree that blockading a country's seaways is aggression - you don't see the hypocrisy of your argument with Israel's compete blockade of Gaza borders and seaways?
