How to Arm Ukraine for Negotiations for
a Durable Peace
A proposed bilateral
meeting between President Volodymyr Zelensky and Russian President Vladimir
Putin will not take place, German Chancellor Friedrich Merz said on Aug.
28. "We have to deal with this issue again today, given the fact that
there will obviously not be a meeting between President Zelensky and President
Putin," Merz said alongside French President Emmanuel Macron as the two
leaders met to discuss peace efforts to end Russia's war against Ukraine.
The German leader's
remarks come following a massive Russian missile and drone attack on Kyiv,
which killed at least 23 people, including four children, and injured another
63.
At his Alaska summit
with Russian President Vladimir Putin, U.S. President Donald Trump treated an
imperial dictator and indicted war criminal like a revered dignitary. His main
goal for the summit, a cease-fire, was rejected outright by Putin, and
his most modest objective for the meeting, a commitment by Putin to meet
directly with Ukrainian President Volodymyr Zelensky, with Trump in attendance,
has thus far been rebuffed by Moscow, as well.
Trump’s intuition
that a deal will require land swaps and security guarantees is
correct; Putin will agree to end the war only if he feels that he has
won Ukrainian territory, and Zelensky will never agree to cede territory
without the promise of protection from a future Russian invasion. But Trump’s
improvisational attempt to negotiate over both subjects at the same time, with
the same groups of leaders, is wrong-headed. Rather than discussing these two
issues with everyone all at once, Trump needs to organize two sets of separate
negotiations. The order in which these negotiations occur will be key to their
success. Trump and his team must first reach an agreement on security
guarantees among Ukraine, other European countries, and the United States. Only
then should Washington encourage a conversation between Zelensky and Putin
about de facto territorial concessions that could bring an end to the war.
Such a diplomatic
two-step will not be easy. Indeed, the United States and Europe may have to
present a security guarantee convincing enough to get Ukraine to agree to an
unpopular compromise: the continuation of Russian occupation of Ukrainian land.
But if Trump and European leaders can hold successful negotiations with Zelensky before
the Ukrainian president sits down with Putin, they have a chance to craft a
lasting peace.

Taking The Leap
An agreement to bring
an end to the war hinges on the ability of Putin and Zelensky alone to reach an
agreement on borders and land swaps. Neither European leaders nor Trump should
be involved in these discussions; neither has the authority to give away
Ukrainian land.
The negotiation will
be very difficult. Putin would have to abandon his maximalist position
that Ukraine withdraw its soldiers from
the parts of the Donbas that it currently controls. Zelensky will never
agree to cede territory to Russia formally—doing so would be political suicide
and could even trigger a coup by his own soldiers—but he could instead commit
to pursuing reunification only through peaceful means. In other words, Russia
would retain its currently conquered territory for now and potentially for much
longer. But the de facto ceding of territory temporarily is preferable to the
de jure handing over of land permanently. In fact, it is a necessary condition
for an end to the war.
Still, agreeing to
cede any amount of land to Russia would be an immense political risk
for Zelensky, one that could easily lead to his ouster in the next Ukrainian
presidential election. The idea remains extremely unpopular among Ukrainians. For
Trump to convince Zelensky, his government, his generals, and the Ukrainian
people to accept such a sacrifice, the Ukrainian president would need something
substantial in return, and he would need it up front.
Insurance Policy
Before Trump can
entice Zelensky to risk his political future on a potential land swap, he must
convince him that the United States and its allies in Europe are willing to
credibly deter a future Russian invasion. Trump has regrettably already taken
off the table NATO membership for Ukraine, which would represent the most
credible security guarantee, since Moscow has never attacked a NATO member. So
for now, the best options are security guarantees negotiated between a
coalition of the willing and Ukraine, which must include Washington and
European countries pledging to help make the Ukrainian army the best-armed
fighting force on the continent, and a commitment among all the parties to the
agreement that they would consider an attack on Ukraine to be an attack on all
of them. To make the security guarantee credible, European soldiers should be
stationed in Ukraine, and American fighter aircraft and other weapons should be
repositioned closer to Ukrainian borders in Poland and Romania.
Trump’s special envoy
Steve Witkoff reported that Trump and Putin discussed
security guarantees in Alaska. But if the United States and Europe are to
offer Ukraine a truly credible deterrent, Russia cannot be involved
in these talks. Trump and European leaders should not repeat the disaster of
the 1994 Budapest Memorandum, in which Ukraine agreed to give up its nuclear
weapons in exchange for a toothless assurance that Russia would not attack it
(and would, in fact, protect it). Seeking Moscow’s permission for security
guarantees would also signal weakness from NATO members and represent a tacit
acceptance that Ukraine is part of Putin’s sphere of influence. Russia’s demand
that it be included as security guarantor against its own aggression must thus
be rejected categorically.
A precedent exists
for ironing out European security arrangements without consulting Moscow:
Washington and Europe did not ask Stalin for the Soviet Union’s permission to
found NATO in 1949. Six years later, the alliance extended an invitation to
West Germany without seeking Soviet leader Nikita Khrushchev’s blessing,
despite opposition from some American strategists, most vocal among them former ambassador to the Soviet Union George Kennan, who
feared it could provoke a major conflict between the Soviet Union and NATO.
President Bill Clinton did not give Russian President Boris Yeltsin a veto over
adding new members to NATO. Nor did President George W. Bush seek Putin’s
permission to expand NATO membership to the Baltic countries and others.

Order of Operations
Negotiations over
security guarantees must be completed before Zelensky agrees to a prolonged
Russian occupation of Ukrainian territory. The details of a deal could be kept
secret until the border negotiations between Putin and Zelensky are completed
and then announced after the new dividing line between Ukraine and Russia is
established. But Zelensky and the Ukrainian people cannot agree to such
significant concessions without knowing what they are getting in return.
Zelensky and his citizens have good reason not to trust the United States right
now, given that Trump has periodically cut off military assistance to Ukraine
and has thus far not implemented new sanctions on Russia. The United States and
its allies must commit to providing meaningful security guarantees before any
progress is made on the borders. Forcing Ukraine to cede territory before
negotiating security guarantees could embolden Putin to restart the war to
derail further talks.
Negotiating an end to
the war in Ukraine remains a long shot. But if any diplomatic resolution
brokered by the United States and Europe is to have a chance, it will require
an approach from Trump more disciplined and creative than he has shown so far.
He must not only convene two separate negotiations; he must get the order
right.
