If Britain had managed to hold on to the Thirteen Colonies and keep the Americans relatively content, could some concept along the lines that Manifest Destiny was in the United States take hold, in the colonies or the entire empire?
If so, could this concept successfully lead to great expansion in North America along the lines of the United States?
Some possibilities:
-Britain/British North America annexes/purchases Spanish/French/Russian territories during/after wars.
-Assuming Britain opens up Japan to Western trade, could a proposal such as that put forward by Commodore Perry in OTL that the US annex Formosa be implemented, possibly leading to far more British East Asian territories.
-Might fillibusters along the lines of William Walker be far more successful in this world, perhaps because this version of Manifest Destiny might include the whole British Empire and therefore be a more global version.
