This strategy is the most commonly used alternative to outright war when one population wants to annex another population's territory.
The strategy is allowed by the United Nations (inexplicably) since conquering a country by means of war is no longer tolerated amongst the international community.
A more successful example of the CBB strategy has been used by the Albanians in their attempt to annex the Serbian state of Kosovo in 1689(Kosovo is part of the original Serb heartland and ancestral homeland of the Serbs).
The same strategy will be used by the large muslim population in the south of France very soon.
(The French were stupid enough to let it happen, so they deserve any problems which come out of an open-door immigration policy.)
