Following WW2, Britain's leadership along with the 99% of the populace support holding and maintaining maximum power in their colonies at any means necessary.
This includes the fact that Britain will want to increase its power in commonwealths such as Canada or Australia and all the other ones to a maximum degree.
Also Britain will try to gain back former colonies such as Ireland and East of the Appalachian Mountains in the USA.
Off course Great Britain will do this all realistically, for ex. it won't commit suicide by attacking USA, but relations will be harmed because of Britain's territorial demands.
This will be first priority on the agenda of Britain's leadership.
How would this affect things?
