Even before Air Force One touches down in Brussels to bring President Joe Biden to three Ukraine summits on Thursday, Western allies have already found what they are looking for - that all too rare sense of unity.
They have Russian President Vladimir Putin to thank for that.
After Russia's invasion of neighbouring Ukraine on Feb. 24 and its brutal war since then over the past month, allies from Washington to Tokyo and Brussels have acted in unison.
And they did it with such staggering speed to hit the Kremlin with unprecedented sanctions and offers of help to Kyiv. That symbolism has the space to trump urgent problem-fixing this week.
With staccato rhythm, Biden will attend a NATO, Group of Seven and European Union summits all within 12 hours of driving around Europe's diplomatic capital from one headquarters to another. The only reason this is possible is because all agree on the major issues so, basically, little time will be needed to paper over deep differences.
On Friday, Biden will be traveling to Poland, the humanitarian hub of the crisis where more than 2 million Ukrainian refugees have arrived, and where U.S. Forces have shored up NATO's eastern flank.
WHAT BIDEN WANTS
Beyond the all-important handshakes, group photos and warm scenes of togetherness, Biden will use his time in Brussels to announce new sanctions against Russia while underscoring the importance of closing possible loopholes in the avalanche of Western measures that have already been enacted.At a time when it is essential to avoid fissures in what's been a largely unified Western response to Russia, the U.S. President will look to press important allies like Poland to dial back the idea of deploying a Western peacekeeping mission to Ukraine. It's an idea that the U.S. And some other NATO members see as too risky as they seek to deny Russia any pretext to broaden the war beyond Ukraine's borders.
For his domestic audience, look for Biden to once again underscore the heroics of the Ukrainian military and volunteers who have managed to hold off an imposing Russian military. He will highlight those remarkable efforts - as well as the generosity of the Poles and other allies at the front lines of the humanitarian crisis - as he redoubles his calls for Americans to stand firm against a Russian war that is spurring gas price hikes and adding to inflationary pressures in the U.S.
Overall, Biden also wants to revel in the scenes of unity at the headquarters of NATO and the EU, where memories of an unraveling trans-Atlantic bond riven with disputes under former President Donald Trump are far from forgotten.
WHAT NATO WANTS
That show of unity will also be paramount at NATO headquarters, where the United States has traditionally given orders, with the rest, sometimes grudgingly, going along.
The summit on Thursday will be a new opportunity for the 30-nation military organization to publicly show that Washington is consulting its allies, something that was sorely lacking under the Trump administration.Biden and his counterparts are expected to discuss the kinds of "red lines" that might draw NATO out of its defensive posture - the world's biggest security organization has mostly bolstered its own defenses since the invasion a month ago - to respond with force.
Nuclear, chemical or a massive cyberattack appear the most likely triggers, but NATO remains wary of any response that might draw it into a full-scale war with nuclear-armed Russia.
