It would hardly be possible for a terrorist group to get a military presence large enough to actually pose a serious threat to US militia forces let alone the actual Army on US soil. Can you even imagine the logistics?
Firstly, who said it's a foreign invasion? The dirty secret of American history is that, historically, Americans have killed far more Americans than anyone else has. You've had a bloody civil war already, and you have plenty of "militia" movements in your past. Domestic terrorism (including police response) has killed more US citizens than all foreign-originated terrorist events combined. But no one talks about that in the US, it seems...
Secondly, please thank Mrs. Madison and tell her she sets an excellent table [http://en.wikipedia.org/wiki/Burning_of_Washington#Events]. Though the specifics of that event won't be repeated in modern times, there is historical precedent. (The odds of which improve dramatically if, as noted above, there's a fifth column movement already in place.)
