By "England" I take it you mean the United Kingdom.We here have not really been a World Power for a while, and now we have left the European Union our economy will no longer support what used to be jokingly called "foreign adventures" or something similar.
Our Navy is depleted, we have an Army somewhat diminished and struggling to recruit, though we have respected and even feared Special Forces, the SAS etc, our Air Force is not too bad.
So yes, the U.K is no longer a World Power. And of course, the J W Org's explanation of what they call Bible prophecies always was laughable, and now makes no sense.
Expect " new light" to accommodate new events and changes in the Political World, but things change so fast that the org is firing at a moving target, by the time their "new light" is published, things will have moved on.
