He might hypothetically agree that the resumption of NATO’s present support for Ukraine (arms, intelligence, logistics, etc.) in the event of another conflict wouldn’t cross Russia’s red lines but he’s unlikely to compromise on the issue of Western troops in Ukraine once the present conflict ends.
Steve Witkoff’s claim that Putin allegedly agreed to the US offering Ukraine “Article 5-like protection” during the Anchorage Summit, which Trump repeated during his White House Summit with Zelensky and a handful of European leaders, raises the question of what form this could hypothetically take if true. Assuming for the sake of analysis that he did indeed agree to this, it’s important to clarify exactly what Article 5 entails. For starters, it doesn’t obligate allies to dispatch troops if one of them is attacked.
Per the North Atlantic Treaty, each member only has to take “such action as it deems necessary”, which could include “the use of armed forces” but doesn’t have to. As was explained earlier this year here, “Ukraine has arguably enjoyed the benefits of this principle for the past three years despite not being a NATO member since it’s received everything other than troops from the alliance.” Arms, intelligence, logistical, and other forms of support have already been provided to Ukraine in the spirit of Article 5.
It might therefore be the case that Putin agreed that such “Article 5-like protection” could be resumed in the event of another conflict without crossing Russia’s red lines. Although Russia objects to Ukraine’s remilitarization after the present conflict ends, it’s possible that it could agree to this too as part of a grand compromise in exchange for some of its other goals being met as explained here. What Russia doesn’t agree to, however, is the dispatch of Western troops to Ukraine after the present conflict ends.
Foreign Ministry spokeswoman Maria Zakharova declared on the day of the White House Summit that “We reiterate our long-standing position of unequivocally rejecting any scenarios involving the deployment of NATO military contingents in Ukraine”. This position isn’t expected to change since one of the reasons behind the special operation is to stop NATO’s expansion inside Ukraine. Western boots on the ground there afterwards would therefore amount to the perceived failure of Russia’s primary goal.
This would especially be the case if they’re deployed along the Line of Contact, but their deployment west of the Dnieper in parallel with the creation of a demilitarized “Trans-Dnieper” region controlled by non-Western peacekeepers as proposed here could hypothetically be a compromise. That said, Russia would prefer for there to only be non-Western peacekeepers, if any at all. The deployment of foreign military forces, regardless of the country, could embolden Ukraine to stage false-flag provocations.
