Economic coercion at sufficient scale is substantively similar enough to war that it should be discussed in war terms.

The analogy captures severity, but it also collapses crucial categories. Sanctions can be warlike in effect while still being meaningfully different from direct military confrontation, alliance obligations, or nuclear escalation risk.

Wars should ideally be fought through finance, logistics, and market exclusion rather than direct battlefield violence when that option exists.

As a moral preference, that is persuasive. The caveat is that economic coercion still pushes costs onto civilians, vulnerable importers, and third countries, so it is not bloodless just because it is non-kinetic.

Preserving the line between severe sanctions and direct NATO military action was strategically more important than satisfying public demands for dramatic action.

That proved to be the durable Western approach. The alliance helped Ukraine massively while still treating direct combat with Russia as a qualitatively different threshold.

Using 'war' rhetoric too loosely can make reckless escalation feel more normalized than it should.

That is a sound criticism in this context. If sanctions, air defense aid, and a NATO-enforced no-fly zone are all rhetorically flattened into the same thing, public debate loses the distinctions that matter most.

The more actors, borders, and militaries involved near the theater, the more the real risk shifts from declared policy to accidental escalation.

That is a sensible systems view of crisis risk. Alliance commitments can turn small incidents into much larger obligations even when no one originally wanted a general war.

The G7 and central banks had enough balance-sheet and policy capacity to stop a Russia sanctions shock from becoming a full-scale financial collapse.

That is basically how the next phase played out. There was real pain, but not the kind of cascading systemic failure Friedberg feared in early March.

If sanctions can meaningfully reduce the odds of direct war, there is effectively no acceptable upper bound on the fiscal or macroeconomic cost to rich democracies.

As a moral claim this is defensible, but it slides too quickly over who actually bears the costs. Emerging markets, poor importers, and politically fragile households did not experience those costs symmetrically.

Even substantial collateral economic pain is justified if it materially reduces the need for direct war with Russia.

That is the logic Western governments followed. The weakness is not the moral intuition but the tendency to skip over distributional consequences once the principle is stated.

The main policy failure risk was not sanctions themselves but the speed and scale of second-order disruptions nobody had really mapped.

That was a real risk and some of it materialized, especially through food, fertilizer, and energy. Friedberg is right that those channels deserved more airtime than they were getting in the first wave of moral consensus.

The global system was close to a broader financial break because of hidden counterparty exposures to Russia-related assets and trade flows.

This was plausible in the moment but did not fully materialize at the catastrophic scale he feared. The humanitarian and commodity shocks aged better than the harder financial-breakdown warning.

Giving Putin the NATO chip earlier would have either prevented the war or at minimum clarified beyond doubt that territorial expansion was the true objective.

The second half is more convincing than the first. It may have clarified intent, but clarity is not the same thing as prevention, especially once Russia had already invested in a much broader coercive project.

Taking NATO membership off the table earlier would likely have been enough, or close to enough, to avert the larger war.

Neutrality was clearly one live issue, but hindsight makes this too confident as a near-sufficient explanation. Russian aims, the status of occupied territory, distrust over guarantees, and Putin's larger ambitions all mattered too.

Even if NATO expansion was partly a pretext, denying Putin that pretext would have meaningfully constrained his domestic and strategic room to escalate.

That is a fair tactical point. Removing an adversary's strongest public justification can matter even if it does not eliminate the underlying ambition.

Once Putin had paid the costs of invasion, a limited exit became much harder because he needed a larger visible gain to justify the gamble.

That matches how the war evolved. Russian demands and annexation behavior became harder, not softer, once the initial blitz failed.

Whatever diplomatic options might have existed before the invasion, they were materially worse after the invasion began.

That is borne out by both the battlefield trajectory and the failed spring 2022 negotiations. Bargaining after a failed attempt to conquer Kyiv was structurally different from bargaining before the attack.
