It would be like if the English decided to arm the redskins in America with colts and repeaters so they could shoot at Americans and stop them from expanding west all while blockading imports and exports from ever touching the water around the United States while everyone else stops trade with you.
Redskins did have firearms and we fought them on and off all through that westward expansion, and we fought and won a war against the English not only for our independence but again not long after, during which I'm sure they did their best to enact exactly what you're describing. We won the wars, and when we didn't like where the indians were, we put them somewhere else.
Angloid colonization worldwide turned to a Quixotic civilizing mission (at least they're not as horny as the Spanish), and the fact that they couldn't get along with the Boers well enough to stop the Zulus overrunning everything makes me question your reductive lust for more whites. I said elsewhere, back when the US had a frontier, we got enterprising, freedom loving immigrants who made this country what it is. Now all the good whites are already here, because the more conservative yet patriotic ones who were left got ground up in two world wars. I'm sure there's some good saffers we could be getting, plus plenty of naive retards and plain weirdos. Like null says, what were these white freaks even doing in Africa; and their failures, even in the face of international pressure, don't reflect well. See also kiwis and strayans, they're not based, not anymore, they're land acknowledging fuckups who heeded the call to turn in the guns.
Also just a thought on equating commies and jews: maybe they did get subverted by the meddling atheist type jews, but then it's funny that they collaborated with the based ethno-nationalist jews in Israel on their nuclear weapons programs.
