This is so excellent. It took me until about the fourth stanza to realize what you meant by "foreign feet". I like the...the...image, the painting you come out with. And you keep it clear without actually mentioning who the "foreign feet" are until the end. That's pretty cool. The only thing I don't like in this is "For their own homes they fear". The rhythym sort of breaks there. Oh and yeah, I like the rhythym of your poem. :)
