How Russia's pipeline politics could split the alliance around Ukraine

Germany's upcoming decision on whether to certify the controversial Russian-owned Nord Stream 2 pipeline is rapidly emerging as a key element in high-stakes diplomatic efforts todissuade Moscow from invading Ukraine.

Delaying or cancelling the $11 billionproject would have a significant impact on the Russian economy, depriving it of $3 billion US in annual revenue.

It also could serve to divide Ukraine's allies as Russia continues to increase the pressure on the former Soviet bloc state.

Nord Stream 2 givesthe new government of German Chancellor Olaf Scholz"some leverage" over Moscow, said Matthew Schmidt, an associate professor and national security expert at the University of New Haven, Connecticut.

"They can exert leverage in a way that works in concert with the rest of NATO," he said. "If they do it in a way that doesn't work in concert with NATO, then that could be a problem. They could put NATO in a bind."

During a recent meeting with NATO Secretary General Jens Stoltenberg, Scholzhinted that his country could reconsider the project "if there is a military intervention against Ukraine."

But the German government is under enormous pressure to relieve soaring natural gas prices and Nord Stream 2 could end up heating up to26 million homes in the country.

Playing the 'pipeline card'

Holding out approval until there's a peaceful resolution to the standoff over Ukraine would allow Russia to walk away with a win, said Schmidt. He said the U.S. did much the same thing to endthe 1962 Cuban missile crisis when it withdrew its missiles from Turkey.

Schmidt said he believes Germany will hold on to the "pipeline card until the very end."

In the meantime, Nord Stream 2remains asource of division and irritation among Germany'sallies.

The pipeline isat the centre of a longstanding disagreement between the United States and Germany.Almost four years ago, then-U.S. president Donald Trump opened up a NATO leaders' summit by attacking the project, warning it would make Germany a "captive" to Russian economic interests.

Nord Stream 2 waspulled back to the centre of allied politics earlier this month when Republicans in Washington pushed a billthat would have imposedsanctions on businesses involved in the project despite President Joe Biden's warning that such sanctions would have harmed relations withGermany at a critical juncture. Senate Democrats defeated the bill.

Ukraine stands to lose significant transit revenue when an existing Russian pipeline crossing its territory is shut down to make way for Nord Stream 2. Kyivlobbied the U.S. Senate to impose the sanctions, while Germany argued against them.

Germany alsohas irritated Ukraine by blocking the sale of some defensive weapons to the government in Kyiv, which has been desperately canvassing the international arms market for high-tech systems to counter a possible invasion.

Schmidt said no one should be surprised at Berlin's caution becausethe country's export licensing policy placesstringent conditions on the end uses of military equipment.

Great power politics is back on a scale not seen since the Cold War, said Roland Paris, a University of Ottawa professor of international affairs and former adviser to Prime Minister Justin Trudeau.

Putin 'turnedup the heat'

He said Russian President Vladimir Putin is "stress-testing the NATO alliance" looking for any division,real or perceived, among allies.

"Putin is flexible and opportunistic. He's turned up the heat to see what happens," said Paris. "If he can succeed in weakening the political unity of the NATO alliance, that will be a major accomplishment for him."

Germany, he said, is "working out" how to deal with the threat ofRussiausingits energy supply as a weapon.

"There have been voices in Germany that have said Nord Stream 2 should continue regardless" of the crisis, Paris said.

NATO allies have been calling for unity as they confront a massivebuildup of Russian troops on three sides of Ukraine, and asMoscow continues todemand that the alliance roll back the deployment of NATO troops in Eastern Europe.

Russia's demands including its insistence on an outright rejection of Ukraine's bid to join NATO have been shot down by the United States and its allies. Recently, Washington put upto 8,500 U.S.soldiers on heightened alert for a possible deployment to Eastern Europe.

Paris said now is the time for Ukraine's allies to send reinforcements. He scoffed at Moscow's claim that sending additional forces represents an escalation of the crisis.

"It's a bit rich, [Russia] having invaded a sovereign country, and now to have over 100,000 troops poised to invade [Ukraine] and then saying NATO reinforcements are somehow the source of a provocation," said Paris, referring to the 2014 Russian invasion of Crimea.
