When Power Meets Its Limits: Why Luck Doesn’t Favor the Devil Forever

By Dennis Ross

In international politics, we often confuse capability with inevitability. The assumption that military superiority guarantees strategic success has shaped countless decisions—and just as often, it has led to miscalculation. As Will and Ariel Durant once observed in The Lessons of History, nature and history do not conform to our moral categories; they reward survival and punish failure. But survival, in modern conflict, is no longer determined by brute force alone.

Recent developments in the confrontation involving Benjamin Netanyahu, Iran, and non-state actors across the region illustrate a more complex reality. Israel retains overwhelming military power. Its capacity to inflict damage remains formidable. Yet power, when unconstrained, can become strategically self-defeating—especially when it collides with adversaries willing to absorb costs and adapt over time.

Netanyahu’s worldview has long been shaped by a belief in decisive force. Rooted in a revisionist Zionist tradition associated with Ze’ev Jabotinsky, this perspective emphasizes deterrence through strength and the necessity of overwhelming adversaries before they can pose an existential threat. In theory, this approach seeks security through dominance. In practice, it risks creating cycles of escalation that are increasingly difficult to control.

The debate over Israel’s objectives in its confrontation with Iran and its regional partners is often framed in conventional political terms: deterrence, containment, or preemption. But this framing misses a critical point. What we are witnessing is not simply a policy choice; it is the collision of strategic doctrines under conditions that have fundamentally changed.

Unlike previous eras, Israel now faces adversaries capable of imposing real costs. Iran’s growing missile capabilities, along with the operational reach of groups like Hezbollah, have altered the balance. The assumption that Israel can act freely without meaningful retaliation is no longer valid. Even the most advanced defense systems cannot guarantee full protection against sustained missile fire. This is not a question of intent—it is a question of physics and scale.

For years, Israeli strategy benefited from asymmetry. It could strike decisively while limiting exposure to retaliation. That asymmetry is eroding. Today, the risk calculus is different. Actions that once carried manageable consequences now carry the potential for escalation across multiple fronts.

This shift imposes constraints—not moral constraints, but strategic ones. When adversaries can respond in kind, the space for unilateral action narrows. This does not eliminate conflict; it changes its parameters. The result is a form of deterrence rooted not in superiority, but in mutual vulnerability.

From Washington’s perspective, this dynamic presents both risks and opportunities. The United States has long been Israel’s primary ally, but it also has a broader interest in preventing regional war. When Israeli actions draw the U.S. closer to direct confrontation with Iran, the margin for error shrinks dramatically. American policymakers understand that escalation is easier to initiate than to control.

At the same time, Iran appears to be preparing for a protracted confrontation. Its strategy is not built on rapid victory but on endurance—absorbing pressure while steadily increasing the cost to its adversaries. This approach complicates efforts to achieve decisive outcomes. It also reinforces a lesson that has repeated itself across conflicts: wars of attrition rarely produce clear winners.

There is another dimension that cannot be ignored. In northern Israel, the displacement of civilian populations—whether temporary or prolonged—has strategic implications. Security is not measured only by battlefield outcomes, but by the ability of a state to maintain normal life within its borders. When that becomes uncertain, the political cost of continued conflict rises.

None of this suggests that Israel’s capacity for force has diminished. It has not. But capacity alone is no longer sufficient to secure strategic advantage. The ability to translate military action into sustainable political outcomes is increasingly constrained.

This is where the notion that “luck doesn’t favor the devil forever” takes on meaning—not as a moral judgment, but as a strategic observation. Systems that rely on unchecked force eventually encounter limits. Adversaries adapt. Costs accumulate. External actors intervene. What once appeared as dominance becomes entanglement.

The current trajectory points toward an unavoidable conclusion: at some point, the logic of escalation gives way to the logic of accommodation. This does not mean reconciliation or resolution of underlying conflicts. It means recognition—however reluctant—that continued confrontation carries diminishing returns.

For Israel, this may require rethinking the balance between military action and political strategy. For Iran and its partners, it means understanding that endurance alone does not guarantee advantage. And for the United States, it underscores the necessity of shaping outcomes before events dictate them.

History does not reward virtue, but it does punish strategic blindness. The lesson is not that power is irrelevant, but that power without limits is rarely sustainable. In that sense, the current moment is not an anomaly—it is a correction.

And corrections, in geopolitics, are rarely gentle.
