Muslimens fædreland er troen, ikke flaget
For Islamists, non-Muslim land is different from Muslim land. Many can never identify themselves with a Western land -- or with a flag or nationality -- even though they may have been born in that land and their families may have lived there for generations.
When people are brainwashed not to identify themselves with a flag and a nationality, it disrupts the human connections and communications that need to take place within communities. It pits the indoctrinated person against the entire society and his own countrymen, and develops an "us versus them" mentality.
This view brings with it a wish for waging jihad against one's birth country. It creates the priority -- if the country attacking it is ruled by shari'ah -- of joining the enemy to fight against one's birth country.
"The homeland of the Muslim, in which he lives and which he defends, is not a piece of land; the nationality of the Muslim, by which he is identified, is not the nationality determined by a government; the family of the Muslim, in which he finds solace and which he defends, is not blood relationships; the flag of the Muslim, which he honors and under which he is martyred, is not the flag of a country; and the victory of the Muslim, which he celebrates and for which he is thankful to God, is not a military victory."
