This should give you a general idea of the meaning, although I didn't catch an idiom or two.
Powerful song, no?

Visit Europe While It Still Stands
(Geier Sturzflug)

If there are U-boats at anchor in the Grand Canal
And rocket launchers in St. Peter's Plaza in Rome
And a carpet of bombs hovers over the bazaar of Ankara
And a Pershing II rises from the hills of Olympus

CHORUS
Then is it too late
That is when nothing more will happen
Visit Europe
While it still stands.

An atomic mushroom rises in the air before the Cathedral of Cologne
And Heaven is filled with the fragrance of neutron waffles weapons.
If the Eiffel Tower in Paris bows toward the west in a final greeting
And a delicate Alpenglow appears in the vicinity of Big Ben
CHORUS

If haute cuisine becomes a witch's cauldron
Where the cook flames his old world from overseas
Then people will laugh and applaud
And the waiter himself will gain a step (?)
Even the waiter will get a kick
What will remain with us other than our culture
We'll wish, "Good appetite."
CHORUS

Then is it too late
That is when nothing more will happen
Visit Europe
While it still stands.
While it still stands.
While it still stands.
While it still stands.
While it still stands.
