The war in Ukraine, we are often told, is a “civil war” involving “rebels” fighting the central government in Kiev. Such restrictive, inaccurate terms greatly misrepresent the conflict, which has already killed over 6,500 and displaced at least 1.4m Ukrainians. Too often, the crisis is talked about as if it’s entirely internal to Ukraine, a domestic affair presumably brought on by language politics, identity clashes and historical grievances. Best, therefore, to leave it alone.

Wrong. Ukraine is waging a war of self-defence against an international aggressor – the Russian Federation – whose conduct threatens our collective security. This war is now 18 months old, and we should know better by now.

Face facts

It’s not as if the signs aren’t clear. Recent weeks have seen another intense spike in fighting in eastern Ukraine. Given all the prior sabre-rattling, nuclear threats and general rhetorical brinksmanship, it takes little imagination to see the conflict expanding beyond Ukraine’s borders into EU member states.

Labelling such a crisis a “civil war” serves no purpose of diplomacy or journalistic balance. It is a failure to serve the public interest. The war needs to be described as it really is.

Fundamentally, this conflict was started and is sustained by Russia’s armed intervention, not a Ukrainian civic collapse. In nearly a quarter century of independence, the Ukrainian public’s support for national unity has been stronger than in many long-established states, among them Spain, Belgium and Canada. As Vladimir Putin has since proudly admitted, it was Russian troops in the spring of 2014 who seized Ukraine’s Autonomous Republic of Crimea.

The Russian military presence has not gone away. In August 2015, Organization for Security and Cooperation in Europe (OSCE) monitors again encountered personnel in eastern Ukraine openly identifying as Russian regular military. These forces continue to lead, train, equip and fight alongside militants advancing Russian neo-imperial and ultra-nationalist ideologies against a government in Kiev espousing respect for democracy, transparency and the rule of law.

To tiptoe around the Kremlin’s armed intervention in Ukraine falls short of the basic standards of war reportage. And it’s absurd to call the Donetsk and Luhansk authorities “rebel” administrations when they would not have come into being and would not continue to function without Russian backing.

We do not talk about a Manchukuo “rebel” administration in 1930s China without mentioning that Japan had invaded it; scarcely anybody pays lip service to the myth of an organic, independent separatist movement in 1930s Manchuria. Nobody should credit Russia’s fiction about “rebel” administrations in today’s Ukraine.

Lest we forget, the purported “rebels” in eastern Ukraine agree. Here is Igor Girkin-Strelkov, a Russian national associated with Russian military intelligence who helped lead the “rebel” movement in eastern Ukraine, speaking only weeks ago: “You are making an idiot or fool of yourself if you think that [the Donetsk and Luhansk Peoples’ Republics] were formed by themselves.”

An important conclusion follows from these facts: the Russian Federation is an aggressor and should be characterised as such whenever we talk about areas of Ukraine that have fallen under the Kremlin’s effective military and political control.

There is no need to report aggression in inverted commas. Since early 2014, the Russian Federation has carried out a host of acts of aggression against Ukraine as defined in Article 3 of the UN General Assembly’s definition of aggression. Russia has invaded Ukrainian territory – Crimea, Donetsk and Luhansk so far – and attacked Ukrainian forces without a shred of plausible legal justification; bombarded Ukrainian territory and killed Ukrainian citizens; and seized territory that belongs within the internationally recognised borders of Ukraine, declaring it part of Russia. These are nothing less than acts of aggression under international law.

Nor do the sham referenda in Crimea in March 2014 or in Donetsk and Luhansk in May 2014 offer any legal wiggle room, since these “Potemkin plebiscites” resulted directly from an invasion of Ukraine by the Russian Federation.

As far as the referendums go, the UN General Assembly, the Parliamentary Assembly of the Council of Europe and the President of the OSCE Parliamentary Assembly all agree they were unlawful and illegitimate. To argue or imply that there has been an act of “self-determination” in any part of Ukraine that calls into question Ukraine’s sovereignty over its recognised territory contradicts the highest available organised expressions of international law.

If editors and journalists are substituting their own judgement of the situation, then they must explain why.

A spade’s a spade

Then there’s the matter of Ukraine’s right to self-defence, which of course is a right of all states. Russia’s aggression against Ukraine is just about the only case where a UN member state has seized and in effect sliced off whole regions of another UN member state.

In its official statements the Kremlin goes further still, repeatedly calling into question the right of Ukraine to continue in its current form, invoking a so-called “New Russia” across vast, strategic tracts of the country, and even threatening nuclear action in the wider context of the conflict.

This is not garden-variety geopolitical grandstanding. When Iraq attacked Kuwait in 1990, it was universally condemned, and Kuwait’s right of self-defence was affirmed. There is no principled reason for responding to Russia’s aggression in eastern Ukraine with different rhetoric or a different description.

It’s time to face reality. The continued escalation of the war in Ukraine poses a serious challenge to international public order. Journalists have risked everything to report events from this war, and we need to stop watering down their reports with euphemism and understatement. We need to call this what it is: a war of self-defence against an international aggressor.
