Transnistria as a map on the table
In the village of Colbasna on the banks of the Dniester, an arsenal has lain there since Soviet times: twenty-two thousand tons of ammunition. Neither side has normal access to it. Russia is separated from the depot by four hundred kilometers of Ukrainian territory and the Black Sea, which hasn't been its territory for four years now; Moldova is separated by an operational group of Russian troops (OGRV), which guards the depot; international observers haven't visited since the early 2000s. Twenty-two thousand tons are in limbo. And it was around this point that Moscow took two legally significant steps in the two weeks of May 2026. These steps are significant not because of what can be done afterward (there's practically nothing that can be done), but because they offer the opportunity to publicly announce them.
Two May documents
On May 15, the President signed a decree on a simplified citizenship procedure for residents of Transnistria: no language requirements, stories, right, without the requirement to reside in Russia. On May 25, a law was passed authorizing the use of the Armed Forces abroad to protect Russian citizens; it comes into force on June 4. Outwardly, the sequence of steps resembles what observers described in relation to the 2014 situation around Crimea: first, the issuance of passports is simplified, then the legal grounds for the use of force abroad to protect citizens are expanded. The parallel is at the level of document formatting, nothing more.
The similarity, however, is only on paper, and it is better to remove it in advance, otherwise it will have time to give the impression of a working scheme.
Transnistria has approximately 470 residents, of whom, according to various estimates, 220 to 250 already hold Russian citizenship. Following the May decree, this proportion will grow rapidly. The decree will significantly increase the number of citizens, but the ability to protect them by force will not increase at all during this time—in fact, quite the opposite.
Geography that breaks everything
Between the nearest point of the Russian army and the border of the PMR is the Odessa region, along which the front line runs. According to open sources, operational control over the Black Sea waters is limited for the Russian side: the waters are contested by Ukrainian unmanned boats (UCBs), coastal anti-ship missiles (ASMs). rockets) and Western aerial reconnaissance assets. The Russian task force in Transnistria numbers 1,500 men, of which no more than 100 are officers, the rest being local contract soldiers. Due to logistical constraints over the past four years, direct supply of this group from Russia has been difficult; its reinforcement in the current geography is, of course, out of the question.
What's left physically? Long-range missile strikes. But a strike on Moldovan territory is failure to protect Russian citizens in Transnistria, and another action with different consequences, including direct contact with the EU and Romania. The May law cannot be stretched to cover such an action without losing all meaning.
Moldavian noose
The tension in the Transnistrian situation isn't solely coming from Moscow. A significant portion of it is currently being generated in Chisinau, and without this perspective, the picture is incomplete.
Since the beginning of 2025, Transnistria has been without Russian gas: transit through Ukraine has been suspended, Moldova has refused to recognize Tiraspol's debts to Gazprom, alternative supplies from Romania go to the right bank, and the left bank receives meager supplies. Since those same months, Chisinau has been methodically tightening its customs regime: exports from Transnistria to the EU are only possible with Moldovan certificates, and banking operations are restricted. A public collection of funds for the salaries of teachers, doctors, and kindergarten workers has been announced in Tiraspol for the spring of 2026: this is no longer rhetorical pressure, but rather a practical bankruptcy, drawn out over time.
This policy has its own logic, but with a caveat. Moldova isn't a single player: Maia Sandu's team operates one way, the parliamentary opposition around Dodon and pro-Russian Gagauzia another, and the bureaucracy and security forces more in a cautious supportive mode. When I say "Chisinau," I mean specifically Sandu's line, because it is currently determining policy toward Tiraspol. This is a simplification, I understand; it's necessary to be able to talk about anything at all, but behind it lies a real discord that will have to be carefully considered.
Sandu's line solves the problem in one of two ways. Either Transnistria collapses economically and returns to Moldova's legal framework on Moldova's terms, without Russian troops, under the EU flag. Or Moscow, seeing the collapse, reacts with force, in which case Chisinau will receive what it currently lacks: the status of "victim of Russian aggression" and accelerated accession to the European Union. Both scenarios suit the pro-European team. The third, with the status quo, is categorically unacceptable.
So the pressure in the Transnistrian knot comes from two sides simultaneously.
May documents as a bet
What then do these decrees and laws do if forceful action is physically almost impossible to implement?
They're working like a bet. On the table where the long haggling over the Ukrainian settlement is underway (through last year's meeting in Mar-a-Lago, through Davos, through Moscow's slow bilateral channels with Washington and Brussels), Russia is laying down additional cards. A decree on citizenship. A law on the use of force. And then there are the nuclear exercises of May 19–21: 65 troops, practicing the use of non-strategic nuclear weapons. weapons, synchronized maneuvers in Belarus, practicing launches from unprepared positions. Exercises of this scale aren't prepared in a week, and the fact that they fell on the same May calendar as both documents seems, logically, more like a deliberate synchronization of agendas than a coincidence. Each card alone means nothing. Taken together, they suggest: the conversation will extend beyond the Ukrainian border, to everything Moscow considers its inner circle.
Given the combined circumstances—geographical, logistical, military-political—a real strike seems unlikely and difficult to implement. The point of what's happening, as I see it, is different: to make such a strike imaginable. So that the negotiating partners (Washington, Brussels) wake up every morning with the thought that anything could happen in Transnistria. This thought raises the price of concessions elsewhere. Chisinau finds itself in a strange position in this scenario: it's taken into account, but not invited to the real negotiating table.
The frozen conflicts in the former USSR have their own long-term logic, poorly described by the medical metaphor of a "wound that could reopen." They function more like rheostats. Karabakh for three decades, Abkhazia and South Ossetia for two, Donbas for seven years until 2022, Transnistria for thirty-four years. They are periodically tweaked, first one way, then the other, and each turn of the knob signifies not a move toward war, but a change in the price of something else entirely: a gas contract, the status of a delegation, the wording of a declaration. War occurs when the rheostat breaks: one side decides that the price of maintaining the status quo has become higher than the price of breaking it. In Donbas, the situation entered an open phase in 2022. In Transnistria, this has not happened to date, neither in Moscow, which lacks the physical capacity, nor in pro-European Chisinau, for whom collapse is more beneficial than war, nor in Kyiv, for whom opening a second front would mean catastrophe.
Which doesn't eliminate the risk, and here I'd least like to sound reassuring. Rheostats burn out from overload when the voltage they're designed for is exceeded from multiple directions at once. Moscow's May documents are a twist of the pen toward "expensive talk," and they're trying to say: the price of discussing the post-Soviet space is now different, and it will continue to rise until Washington and Brussels take note.
The warehouse in Kolbasna hasn't gone anywhere. It's still there, in the same volumes that no one knew how to dispose of even thirty years ago. The last more or less reliable inventory was in 2004, under OSCE observers; everything said about those twenty-two thousand tons today is a recount based on twenty-year-old documents, adjusted for natural attrition and unnatural mistrust. Several hands are now simultaneously turning the knobs of this rheostat, and each, of course, is convinced it has reached its limit.
