So with so much at stake today, can the EU and United States trust in Poland’s good judgment when it comes to forging a new transatlantic settlement? The answer is yes, implicitly, but the alliance needs to recognize a tick. For Poles, international relations can mean just that: international relationships, ties, and loyalties. Sometimes, Poland cannot help but give greater weight to loyalty than to substance.

Take the sharp public statements from Warsaw since the beginning of the Ukraine crisis. For many in the West—Berlin and London—the shrill tone can be off-putting. But this is the point. Such words are meant less as statements of intent than as tests of loyalty. Warsaw makes a purposely divisive statement, and the response it wants to hear is one of unfettered support.

Some states get this. U.S. President Barack “Here’s $1 billion” Obama and French President François “The United States shouldn’t have a monopoly on reassurance” Hollande are the ones making all the right noises. France in particular has been generous in giving cheap but highly symbolic shows of support, be it French participation in NATO’s 2013 Steadfast Jazz operation in the Baltics or Paris’s recent growling about the need for reassurance.

France’s moves have paid off. The Poles are now trying hard to understand and even excuse a deal by Paris to supply Mistral-class boats to the Russians. And they are affording the French a kind of honorary membership in “New Europe” alongside the Balts and Romanians. (The logic is that precisely because France didn’t get caught up in Iraq, it now has the appetite to defend Western values.)

This weltanschauung could clearly have an impact on the way issues are debated by the allies. Poland will permit loyal states like France or the United States to broaden the agenda away from collective defense—even to mention the South and the need for pragmatic cooperation with Russia. But suspect countries may meet resistance, even when they think they are echoing wider Polish priorities.

If Berlin, for instance, tries to shift the transatlantic debate to energy security or democratic transition, Poland will hear only the sound of Germans trying to wriggle out of their military commitments. And although the UK might get away with talking about Syria (which signifies “awareness of security issues”), the words Tunisia (“democratic transition”) or Libya (“energy”) could be red rags to a bull.

This privileging of loyalties over substance is not just the result of Poland’s history of abandonment by the West but also the lesson from the country’s recent integration into it. After twenty-five years spent adapting to Western organizations, Poland knows well their hypocrisies. Leaders in Warsaw know that sometimes their partners are just telling them what they want to hear, and they believe—not unreasonably—that this is how things work.

That means the allies must learn to tell where Poland is doing the same. They must learn to differentiate between Polish statements or actions on, say, NATO enlargement, domestic missile defense, or national defense spending that are a genuine show of loyalty and those declarations that are only dressed up as such. Poland is scared of losing its partners if they see its weak points.

So, as a medium-sized, frontline state that has invested heavily in both an Atlanticist and a Europeanist approach and has found both wanting, Poland sees more clearly than most what is at stake. Moreover, it has the resources and the nous to play midwife to a reasonable new transatlantic settlement.

But, like all states, Poland needs sensitive handling. Otherwise, any new transatlantic deal might consist of hot-air reassurance measures from France and the United States and very precise “trip wire” territorial defense commitments demanded in response to British and German shakiness. This is a volatile combination. Add to that Poland’s occasional propensity to name and blame others rather than address its own weaknesses and insecurities, and we might well have the trigger too.
