Realistically, in geopolitical terms, The Caliph's hypothetical journey to Rome is also a joke. IS is surrounded by hostile powers, from Iran and Turkey to Egypt. If the Men in Black decided to cross 300 kilometers of desert to attack King Playstation's realm, also known as Jordan, they would be all droned to death.
So now that he's announced himself as the new Osama, The Caliph had better watch his back. Most probably he's a one-trick camel. He might realize he's got a better shot at stardom by branding himself as the second coming of Michael Jackson and start doing the Moonwalk (the jihadi remix). What he will certain realize is that Bashar al-Assad's Syrian Arab Army is the only game in town on the Syrian side in terms of attacking and inflicting serious pain on IS. And on the Iraq side there are even more options.
All coup rumors notwithstanding, al-Maliki will most likely remain in power in Baghdad. And he will be fully weaponized not only by Tehran but also Moscow. The Iranian Revolutionary Guard Corps is already involved in helping to build what could be described as National Guard brigades. They will go after IS big time. In a pincer movement, attacks from Syria and from Iraq could destroy most of IS six months from now.
