The threat of a Russian invasion of Ukraine has sent NATO
countries scrambling to provide military support to Kyiv. In recent weeks,
Spain, France, Estonia, the United Kingdom and the United States among others
have provided varying kinds of military support to Ukraine in anticipation
of Russian aggression.
NATO is under no treaty’s obligation to defend Ukraine
because the ex-Soviet country is not a member of the alliance, but the group
has made clear that it stands with Kyiv and has called on Moscow to de-escalate
tensions.
Some military movements appear to be
posturing, aimed at deterring Russia from any aggressive actions, but
other steps appear to be prepared for a serious conflict. Either way, experts
say, the assistance could show Russian President Vladimir Putin that the
cost of an invasion of Ukraine is too great.
“There's clearly a sense that the military support provided
to Ukraine would help Ukraine raise the cost to Russia of military aggression,”
said former US Ambassador William Courtney, a senior fellow at RAND
Corporation.
Ukraine has asked to join NATO, a move that is staunchly
opposed by Russia. Russian officials have demanded that NATO not extend further
east, but the alliance has rebuffed these demands. The Kremlin has used this
refusal as a justification to amass forces at the border, claiming unspecified
security concerns.
Russia has amassed at least 100,000 troops near its
border with Ukraine, and US officials have warned that an attack could likely
occur by mid-February.
In recent years, the Ukrainian forces have been able
to increase operability and protect itself against another invasion.
Still, the Russian military is far more dominant and capable than its
opponent.
Courtney confirmed that NATO has no formal obligation to
defend Ukraine, but added that the West’s military support to the Eastern
European country has been “quite substantial” since 2014.
At the time, Russian forces invaded and annexed the Crimean
Peninsula.
“Europe and the United States, over time, developed an
increasing desire to help Ukraine advance internally both through reforms
democratic and economic reforms, and also to move closer to the West which
seems to be Ukraine's interest,” he said.
One goal of aiding Ukraine is centered on the concept of
“porcupine defense,” the idea that a country makes itself as difficult to
invade as possible.
“You provide security assistance and arms that are lethal
that complicate Russia's ability to take large parts of Ukraine without getting
beaten up in the process,” said Rachel Ellehuus, deputy director of the Europe,
Russia and Eurasia program at the Center for Strategic and International
Studies.
“So, they can certainly withstand a Russian incursion for a
limited period of time, but not forever,” she continued.
This method, combined with the alliance’s threats of severe
economic consequences should Russia invade, could make Putin think twice about
doing so.
“The issue is helping to deter Russian aggression by making
clear that the cost to it economic, military and the human costs of casualties
will be greater than maybe expected before,” Courtney said.
While the alliance is behind Ukraine, countries thus far
have varied on the extent of their support.
Over the past couple of weeks, Denmark decided to send
four additional F-16 fighter jets to Lithuania for air policing and a
160-man frigate in the Baltic Sea. France, for its part, has offered to
send troops to Romania.
The United Kingdom also announced that it is sending
Ukraine light, anti-armor defensive weapons systems, as well as a
small number of UK personnel to provide training.
Meanwhile, Estonia, Latvia and Lithuania recently received
approval from the US to send American-made weapons to Ukraine for additional
defense.
Estonia is providing Javelin anti-armor missiles, while
Latvia and Lithuania are providing Stinger anti-aircraft missiles and adjacent
equipment.
“We sincerely hope that Ukraine will face no need to use
this equipment and call on Russian Federation to seize its aggressive and
irresponsible behavior,” the Baltic nations said in a statement.
Spain announced that it is sending warships to bolster
NATO’s naval forces in the Mediterranean and Black Seas and is mulling
sending its own fighter jets to Bulgaria.
But countries sending assistance must strike a delicate
balance — helping Ukraine without doing anything that could provoke the Kremlin.
Charles Kupchan, a senior fellow at the Council for Foreign
Relations, explained that recent efforts to provide assistance have been
defensive in nature for this reason.
“Given that diplomacy continues and that the preferred
outcome by NATO countries is a diplomatic resolution to the conflict, NATO
members are trying to find the right balance between improving the capabilities
of the Ukrainian military to resist Russian aggression and taking steps that
the Russians would see as a provocation,” Kupchan said.
Further complicating matters is uncertainty about how Russia
would invade Ukraine, should it choose to do so.
Moscow has largely positioned troops along
Ukraine’s northeastern border. On Tuesday, it announced that it is moving
troops to Belarus for military drills that are scheduled for next month, when
the West fears an invasion could occur.
The drills put more pressure on NATO nations, as it
puts Russian troops on Ukraine’s northern neighbor, giving Putin more options
for a possible invasion.
“I think the dynamic really changed when Russia sent forces
into Belarus,” Ellenhuus said. “A lot of allies now worry that Russia is
somehow preparing to invade Ukraine, both from the south and then also from,
from Belarus.”
A Russian invasion of Ukraine could trigger a rush to ensure
that countries on its eastern flank are defended.
The US, for its part, has no intentions of sending troops to
deter an invasion, but has said if Russia invades, then it would send troops to
bolster NATO’s forces along the Eastern Flank.
President Biden has also repeated several times in recent
weeks that if Russia decides to invade Ukraine, the US will slap devastating
economic sanctions on the country. Vice President Harris echoed this same
sentiment in an interview with Savannah Guthrie earlier this week.
The US military has already sent the USS Harry S. Truman
aircraft carrier strike group to take part in a NATO naval exercise in the
Mediterranean, though Pentagon officials insist the drill are not in response
to Russia’s recent aggressions.
