Who cares? You can read anything you like into a song, and the author's intentions don't even matter anymore, beyond a certain point. This is like asking whether "Puff, the Magic Dragon" is about pot--who cares what the "right" answer is! If it's meaningful to you with your interpretation of it, then your interpretation is "right."

A friend of mine does "The Foggy Dew" (the Easter Uprising version) with an Irish band he's in, and he spins it so that it focuses more on the soldiers than on England. He sees the last verse as talking about post-traumatic stress syndrome, and whether he's "right" or not in his interpretation, he sings it as well as I've heard it played, and it comes across to the listener--which is the point. Debating whether some detail is "correct" is silly. Songs by their nature are open to interpretation, and they can always move beyond their author's original wishes.
