Why do you need to be energy independent to take on Pakistan? What energy do you import from Pakistan?
Who wants to take on Pakistan? For what gain? They are both both useless ingrates and a treacherou ally in Afghanistan. The country is a mess and has nukes.
What energy do you import from Pakistan?
None, but we buy it from other Islamic countries, funding jihadis in the process when we have plenty of coal, oil and natural gas and that more could be gotten from Canada and Mexico to meet our near term needs until we became completely independent and an exporter of coal and natural gas. Did you ever hear of fracking? It's a keyword.
