Well the emperor died on the walls defending the city. His body was never found. I wouldn't call them weak-kneed.
Couldn’t see any of our leaders doing anything remotely like that. Most would become Barney Franks instead.
His stand was brave yes...but how many centuries did they fight muslims? 8? 9?
In that period they lost and continued to lose. Syria, Anatolia, Egypt, Libya, Jordan were all lost.
And now it looks like they are about to give up their own ancestrial lands with the most recent riots there as they continue to bow down.
