In USA , it is ‘America’.
Throughout the old British Empire , it is ‘God Save the King/Queen’ .
And apparently something akin to that for the Kaiser, back in the day, as you posted .
Remember that the royal ‘Windsor’ family of the UK and elsewhere , were imported from the same region as the Kaiser , and are likely related , as they were to the ill-fated family of the late Czar of Russia , whose pleas for asylum a century ago were ignored or rebuffed by the Windsors .
