Rule britannia af James Thomson

Hej allesammen!
Har læst digtet "rule britannia" af James Thomson som jeg skal bruge i en sso i Engelsk. Men ville gerne høre jeres bud på en kort tolkning/analyse.
Håber at høre fra jer!

When Britain first, at heaven's command,
Arose from out the azure main;
This was the charter of the land,
And guardian Angels sung this strain:

Rule, Britannia, rule the waves;
Britons never will be slaves.

The nations, not so blest as thee,
Must, in their turns, to tyrants fall:
While thou shalt flourish great and free,
The dread and envy of them all.

Still more majestic shalt thou rise,
More dreadful, from each foreign stroke:
As the loud blast that tears the skies,
Serves but to root thy native oak.

Thee haughty tyrants ne'er shall tame:
All their attempts to bend thee down,
Will but arouse thy generous flame;
But work their woe, and thy renown.

To thee belongs the rural reign;
Thy cities shall with commerce shine:
All thine shall be the subject main,
And every shore it circles thine.

The Muses, still with freedom found,
Shall to thy happy coast repair:
Blest isle! with matchless beauty crowned,
And manly hearts to guard the fair.
