Zelensky demanded a minimum of 200,000 European peacekeepers during the panel session that followed his speech at Davos, which itself saw him propose that France, Germany, Italy, and the UK combine their forces with Ukraine’s in order to counter Russia’s in nearly equal numbers. He also suggested that Trump will abandon Europe in order to cut a deal over Ukraine with Russia and China. The subtext is that they should organize a large-scale peacekeeping mission before that happens.
They’re unlikely to accede to his demand, however, for the same reason that the UK is unlikely to actually establish a military base in Ukraine like it agreed to explore doing in their new 100-year partnership pact. None of the Europeans want to risk a war with Russia where they’d be left fighting on their own without American support, not even the nuclear-armed UK and France, since Trump isn’t expected to extend Article 5 mutual defense guarantees to allies’ forces in third countries like Ukraine.
He, who loves having as much control over everything as possible, naturally wouldn’t feel comfortable knowing that others could provoke a war with Russia that might then drag in the US. Trump’s grand strategic goal is to wrap up the Ukrainian Conflict as soon as possible so as to prioritize his far-reaching domestic reform plans while “Pivoting (back) to Asia” to more muscularly contain China. Anything that could come in the way of that agenda, especially others provoking a war with Russia, is anathema.
That said, it can’t be ruled out the Europeans might assemble a large-scale force on Ukraine’s Polish and Romanian borders for rapid deployment in the event of future hostilities, regardless of whether this is coordinated through US-controlled NATO or outside of it. For that to happen, however, Polish–Ukrainian ties would have to improve (Zelensky ignored Poland in his speech despite it having NATO’s third-largest army) and Romania’s populist frontrunner would have to lose May’s presidential election rerun.
Moreover, Europe would need to make meaningful progress on building the “military Schengen” for facilitating the movement of troops and equipment through the bloc to its eastern borders, otherwise whatever it assembles on the Ukrainian frontier and then sends across it would be logistically vulnerable. Polish-Ukrainian ties haven’t yet improved, Romania’s presidential election rerun hasn’t yet happened, and the “military Schengen” remains mostly on paper, all of which work against Zelensky’s plans.
Consequently, the likelihood of the Europeans assembling a large-scale force on Ukraine’s Polish and Romanian borders anytime soon is low, let alone them unilaterally deploying peacekeepers – whether 200,000 or just 2,000 – to Ukraine without prior US approval. Nevertheless, Zelensky’s Davos speech and panel session might serve to plant the seed of “ambitious thinking” in European policymakers’ minds, which could lead to them initiating such discussions with the US.
