How can we follow ISIS 'to the gates of hell' if we 'don't have a strategy yet'?

Scrolling my through my Twitter feed (@daren_j_zehnle) a few moments ago, I saw a quote attributed to Vice President Joe Biden, with a question:

Per VP Biden the U.S. will follow ISIS “to the gates of hell.” Does Syria = hell?

I will not connote Syria with hell; the country, after all, was home to Christians for many years.

Mr. Biden spoke these words earlier today when speaking about the beheading of Steven Sotloff. The words quoted above were said, of course, in the context of a full sentence:

We take care of those who are grieving. And when that's finished, they should know we will follow them to the gates of hell until they are brought to justice because hell is where they will reside. Hell is where they will reside.

I would really like to believe the Vice President's words that we do indeed take care of those who grieving, especially the tens of thousands of Iraqi Christians grieving the brutal executions and rapes of their family and friends, but given the President's admission a few days ago that "we don't have a strategy yet" regarding the Islamic State, Mr. Biden's words are hard to believe.

Perhaps it's time we found a strategy.

UPDATE:

The Catholic Near East Welfare Association has provided an update on the current situation in Iraq and quotes a letter from Sister Maria Hanna, Superior General of the Dominican Sisters of St. Catherine of Sienna, a community of Sisters in Iraq, who says: "We entered the fourth week of displacement. Yet, there is nothing promising at all."
