Raphael Perl and the First Unreserved Preemptive Strike

By Desmond Okafor · September 11, 2026

Hundreds died in East African embassies while Washington pivoted toward a doctrine of preemption that remained a legislative study for years

Blood stained the streets of Nairobi and Dar es Salaam in August 1998, where hundreds of embassy employees and civilians were slaughtered in coordinated blasts. The cost of this failure was measured in shattered lives and the sudden, violent realization that the existing security apparatus was useless against a new kind of borderless war.

In the immediate wake of the carnage, the United States did not look inward at the security lapses that allowed the attacks to happen. Instead, it looked toward targets in the East. The record, which survives as a curated description of a September 1998 report, establishes that Washington launched retaliatory strikes against training bases and infrastructure in Afghanistan used by groups affiliated with Usama bin Ladin, the founder of al-Qaeda who would later orchestrate the September 11 attacks. The strikes also hit a plant in Sudan, a Northeast African country, which the U.S. charged was producing a critical component for nerve gas.

"Unreservedly Acknowledged"

While the missiles were still settling in the desert, the Congressional Research Service—the nonpartisan research institute under the Library of Congress that provides analysis for members of Congress—was already analyzing the legal shift. The report was authored by Raphael E. Perl, a lawyer and psychologist who had previously served as the chief interrogator during the Malmedy massacre trial following World War II.

Perl’s report is not a mere summary of military action; it is a marker of a doctrinal pivot. According to the record, the report asserts that these attacks represented the first time the "U.S. had unreservedly acknowledged a preemptive military strike against a terrorist organization or network."

This is the crucial line. To acknowledge a strike as "preemptive" is to move the trigger from the moment of attack to the moment of suspicion. It is the transition from defense to a permanent state of offensive anticipation. The public record establishes that bin Ladin had already used Afghanistan as a base for his global jihadist operations, but the decision to strike those bases—and the Sudanese plant—was framed as a "new policy direction."

The Sudan Nerve Gas Plant

The strike in Sudan reveals the most aggressive edge of this shift. The public record shows the U.S. targeted a specific facility it claimed was producing nerve gas components. However, the record of the CRS report summarizes the conclusion—that the U.S. "charged" the plant was involved in chemical weapons—without detailing the evidence.

This is where the document’s silence speaks. The desk's reading is that the operational intelligence sources, whether they were human assets in Khartoum or signal intercepts, were omitted from the legislative summary to maintain plausible deniability. If the evidence for the nerve gas plant was thin, the report’s framing of the strike as a "policy direction" effectively launders the intelligence failure into a strategic choice.

Furthermore, the pattern suggests that the sovereign agency of Sudan and Afghanistan is entirely erased. In the eyes of the CRS, these nations are not geopolitical actors with diplomatic responses or legal protests; they are merely geographic containers for targets. By treating these countries as empty space, the report justifies the violation of their borders as a clerical necessity of the "new policy direction."

Domestic Costs and Civil Liberties

Perl did not only look at the targets abroad. The record shows the report examined the internal consequences of this shift, specifically "U.S. preparedness for domestic and overseas attacks" and the "potential restrictions on civil liberties."

There is a bitter irony here. The public record shows that the very "preemption" being analyzed by the CRS in 1998 would eventually be scaled into the global war on terror, leading to the systematic erosion of privacy and the normalization of extraordinary rendition. Perl was identifying the risk of "civil liberties" restrictions at the exact moment the machinery for those restrictions was being built.

The desk's reading is that the report obscures a massive intelligence failure. By framing the August bombings entirely as a catalyst for a "new policy direction," the record avoids the question of why the embassies in Kenya and Tanzania were so vulnerable in the first place. The focus on the "preparedness" for future attacks serves as a convenient screen, shifting the conversation from how we failed to how we will strike next.

The Precedent of Liability

If this file is shaped the way it looks, it is an exercise in managing the liability of a dangerous precedent. The report treats preemption as a matter of "preparedness" and "policy shift" rather than a strategic risk to international law. By analyzing whether the U.S. was "prepared" for the fallout of such strikes, the CRS was essentially providing a risk assessment for a policy of unilateral aggression.

The pattern suggests the report suppressed inter-agency conflict. The public record knows that the State Department and the Department of Defense often clashed over the diplomatic costs of "surgical" strikes in sovereign nations. Yet the record presents the response as a singular, focused policy. This erasure suggests that the internal disputes over the legality of the Sudan strike were deemed too volatile for a legislative research report.

The desk's reading is that the 1998 strikes were not a response to terrorism so much as they were a laboratory for the next decade of American foreign policy. The "unreserved acknowledgement" of preemption mentioned by Perl was the opening of a door that could never be closed. It established the logic that any nation, or any facility within a nation, could be targeted based on a "charge" of future intent, provided the target was framed as a "network" rather than a state.

What a full release of the underlying intelligence would show is the gap between the "charges" made against the Sudanese plant and the actual evidence held by the CIA and the Pentagon. The withheld pages are protecting the specific failures of the intelligence that justified the strikes, ensuring that the narrative remains one of bold leadership rather than guessed-at targets. The cost of this precedent was paid first by the civilians in Sudan and Afghanistan, and eventually by the global order of sovereign borders, all to ensure that the failure of embassy security in Nairobi and Dar es Salaam never had to be truly answered.
