Opinion | Russia’s invasion of Ukraine shows fearful nations nuclear weapons mean safety
- On top of the human cost of the war in Ukraine, international agreements and nuclear non-proliferation are suffering as more governments look to go nuclear
- The fate of Libya and Ukraine is likely to keep Iran and North Korea on their current paths and sway the likes of Saudi Arabia, Japan and Taiwan

Ukraine signed on to the Minsk II agreement in February 2015 in an effort to end hostilities with Russian-backed forces in the Donbas region. The last-minute calls by Western leaders to invoke the agreement as war approached last month, as well as Putin’s denial of its existence, only highlighted the deal’s fragility and the danger of basing one’s security on the abstract principles of international law.
The deal’s undoing was that Moscow was party to the negotiations and influenced its outcome on paper, but since Russia claimed to not be directly involved in the conflict, it could shirk implementing the agreed changes. Essentially, it had all the power and no responsibility. If things did not proceed as Moscow wished, it could ditch the agreement as void and resort to violence again, which it did.
The takeaway for vulnerable states is that peace accords signed with hostile actors who are impervious to international norms offer no protection. The infinite interpretative wiggle room of international agreements allows aggressors to walk back commitments signed on paper while marching into your territory.
The same is true for the Budapest Memorandum, the violation of which has now damaged the cause of non-proliferation. In 1994, under pressure from a Washington high on its post-Cold War moment, a newly independent Ukraine did what seems unthinkable now. It handed over its entire nuclear arsenal to Russia in exchange for commitments from Washington, London and Moscow to “refrain from the threat or use of force against the territorial integrity or political independence of Ukraine”.
