As if not troubled enough by President Trumps attacks, a new debate is heighteningtensions in the intelligence community. The Pentagon has started to assess whether it is time todivide the leadershipof the National Security Agency and U.S. Cyber Command.Such a move is dubious: Is change necessary? Can the IC tolerate another shock?

A look overseas to the Israeli case could provide some insight.

According to that plan, the new directorate would absorb responsibilities and resources from both Unit8200(the IDFs signals intelligence or SIGINT unit, equivalent to the NSA), as well as the Computer Service Directorate (equivalent to the Joint Staff J6). A fierce internal debate has emerged, with several (including the head of AMAN, the Intelligence Directorate) arguing that all cyber activities should remain under AMANs responsibility, while others insist that there is an acute need for a dedicated cyber directorate.

In early 2017, Lt. Gen. Eizenkot announced that the establishment of the Cyber Directorate would be postponed until further notice, and declared that AMAN would handle offensive and information collection elements in cyber space, while the Cyber Administration would come under the Computer Service Directorate, focusing mainly on defensive activities.

The reasons that led Lt. Gen. Eizenkot, who is considered a level-headed officer, to reverse his 2015 decision are highly relevant to the American case.

From a strategic standpoint, the implications of the cyber domain on present and future battlefields are still ambiguous and constantly changing; so too are their effects on traditional kinetic challenges. The inter-relations between the physical and virtual domains are still in flux, with grave ramifications on the nature of threats, and the measures needed to cope with them.

These changes are highly relevant to the way the IC reacts and adapts. The vast majority of the NSAs current collection activities are most likely executed through and with the cyber domain. Though traditional methods (such as phone tapping) are not dead, it is safe to assume that cyber is more dominant than ever, and will only continue to grow over more traditional domains and methods. Furthermore, given the specific characteristics of the cyber domain, it is difficult to distinguish between types of cyber activities (e.g., collection vs. attack). Separating those in charge of SIGINT and those in charge of cyber doesnt make sense.

as the last few years have taught us, the Wests adversaries have themselves transitioned to the cyber domain. With Russias (alleged)interventionin the U.S. elections, theSnowden affair, HAMAS and Irans extensive use ofcyber-related techniques, Chinesetheftof F-35 plans, and ISISssophisticated useof the virtual domain, this may not be the right time for radical changes.

Separating the NSA and the Cyber Command would inevitably create a long transition period, during which U.S. cyber capabilities would be negatively affected. Disputes over missions and responsibilities, coordination issues, transition of manpower, and lack of sufficient resources in one or both entities would jeopardize U.S. cyber resilience in the short term at the very least.

Finally, with Trump trying to aggressivelyredefinerelations between the IC and the executive branch, the last thing the community needs at this moment is another shock. A decision to separate the NSA and Cyber Command would create an all-out war within the IC and the Department of Defense, since no sane commander would agree to surrender responsibilities and resources to another organization.

The NSA itself would lose not only prestige but also relevancy, and presumably try to torpedo the move. If any change is needed at all, it would require a different approach: the cyber component should gain supremacy over any other type of SIGINT activity, as this will be the not-too-distant future reality. Until then, NSA-Cyber Command relations should remain untouched.
