That is a disgusting lie that I will not even respond to. Our enemies will do anything to keep their rightful King Joffrey off the Iron Throne, that sure makes things great for Usurper Stannis wouldn't you say?
there is a difference between fighting on home soil and fighting in the Riverlands
. If I were for example attacking the Stormlands from the west then that is a huge advantage for the Stormland faction, if you were attacking Arryn from the west that is a huge advantage for Arryn, but you have no convinient mountain passes, all you got are river chockholds..... which I will control anyhow
