To dissemble radical islam is going to require radical measures of Christianity, and this time around I at least can know nobody down the road will question why it was done.
Threatening the Vatican, for God's sake. Idiots.
One of the nice things about Catholicism is that we're not beholden to a geographical spot on the globe. As long as some priest, somewhere in the world, in some dank cellar in China or somewhere in the nether reaches of Iceland is celebrating Mass, the Catholic Church is open for business.
So, yeah, the Vatican holds a lot of symbolic value, but it's not like the necessity of Jews and Muslims to call Jerusalem their capital...It's the ultimate portable Church.
