At a SO/LIC conference sponsored by NDIA in DC last Winter, a SOCOM brief introduced a new acronym MIDLIFE as an expanded version of DImE to illustrate the instruments of national power that SOCOM considered using against terrorism and insurgencies.

The additional letters L, I, and F stand for Law Enforcement, Information Warfare and Financial actions.

This makes sense. You need Law Enforcement to take down cells and support structure in nations where military force is inappropriate. Information Warfare is certainly valid. And actions in, with, and by Financial institutions are necessary to detect, track and act against the enemy's finances.
