all national perspectives regarding the support for Ukraine, with questions looming over
the end of financial and military aid, and the fear that Trump might impose a ceasefire on
Ukraine against Kyivs will (and potentially against European interests) and aim for a reset
with Russia. This is particularly true for Ukraine and EU/NATO countries bordering
Ukraine and/or Russia, even if they might generally welcome Trump's push for more bur-
den-sharing in defence spending. Trump's statements along the campaign trail, his contro-
versial interactions with Zelenskyy, and the hostility of influential right-wing groups like
the Heritage Foundation towards continuous support for Ukraine add to the worry. The
more - and the faster - the U.S. would withdraw support from Ukraine, the more pressure
will be on national budgets of European countries to step up – without them being able to
fill the gap left by the US. However, there is speculation that Trump might be willing to
agree to a transition from grants to loans, allowing Ukraine to continue to fight. Beyond
Ukraine, there are also individual concerns regarding Trump’s policy towards regions of
particular interest, such as the Western Balkans (e.g. for Bulgaria) or Northern Africa (e.g.
for Spain). Another concern in the defence field is that Trump might question the added
value of Allies and Alliances as such, impose a transactional reading of the transatlantic
relationship and question the credibility of NATO’s Article 5. This fear is particularly per-
ceptible in those countries geographically close to Russia and with negative historical ex-
periences with Russia, like the Baltics, Nordics and Poland. Additionally, NATO could be
embroiled if not divided in debates such as the 2 percent (or more, as agreed in Vilnius)
per GDP defence spending target, with different views on how the EU and European coun-
tries in NATO should react to Trump’s transactionalism. While all allies agree that Europe-
ans need to do more and improve their capacity to act, they disagree on how to achieve
this. Many countries, such as Norway and Germany, make an effort to reach the 2 percent
defence spending before the NATO Washington summit 2024, as a kind of preventive pol-
icy for a potential Trump presidency. There are, however, also nuances: Some experts re-
port that their countries are less concerned about being directly affected, either because
they believe to have a credible deterrent themselves (such as France) or because they
have recently strongly increased defence spending (such as Poland).
On trade and wider economic relations, European countries are clearly anticipating dis-
ruptions in transatlantic relations, including tariff wars, anger over possible unilateral de-
cisions to extend technology controls against China, and a potential extraterritorial appli-
cation of all kinds of U.S. legislation (financial sanctions, export and investment controls).
These factors could have far-reaching implications for global trade and investment flows.
Such concerns are particularly pronounced in countries whose economic models rely
most strongly on global trade, such as the Netherlands, Germany, Ireland or Sweden.
Finally, on a meta level, the differences and nuances point to a major strategic challenge
for European policy makers if Trump returns to the White House – on how to create and
maintain unity visa-a-vis what remains for most European countries an indispensable ally.
On first sight, the large overlap in concerns leads some to “hope for the best”, a Trump
Presidency as a unifying factor. Pushed towards stronger self-reliance – some dare say
strategic sovereignty – a less trustworthy U.S. could lead to a renewed sense of shared re-
sponsibility among Europeans, inside the EU, but also with crucial partners such as the
UK. It could also give a new sense of urgency to long derailed European defence efforts.
A closer look at the nuances, however, underlines that such a push for unity is far from
guaranteed. On the contrary, even the subtle differences between European countries
make them susceptible to divisions, as does the willingness to engage in transactional ac-
tions to maintain security support. The more likely scenario, given this exercise on the
range of views across Europe, seems – in our view – to be the opposite: if the U.S. were to
challenge European commitments, Europeans would not react in unity but separately –
especially on defence issues, but also on trade and economic security – and would be
