NATO's expansion explained: Sweden's wait, Canada's role and Russia's response

At its simplest, the latest news about the expansion of the North Atlantic Treaty Organization (NATO) is this: Sweden wants in.

But look closer and the geopolitical blowback and deal-making expands to include a map's worth of key players, including Canada.

Here's how it all breaks down.

Russia invades Ukraine

In early 2022, Russian President Vladimir Putin ordered his military deep into Ukraine, in an escalation of a conflict that began in 2014.

Putin said during his televised address announcing the invasion that it was due in part to the eastward expansion of NATO — the military alliance of Canada, the U.S. and much of Europe created in 1949 to counter the Soviet Union. It originally had 12 members but by the time of the Russian invasion had 30.

If Putin had intended to slow NATO's growth, his invasion had the opposite effect.

Finland and Sweden apply to join NATO

Sweden and Finland had long pursued policies of formal military non-alignment, but Russia's invasion of Ukraine prompted a rethink.

Finland has a 1,300-kilometre border with Russia, and the Swedish island of Gotland lies just 300 kilometres from the home of Russia's Baltic Fleet.

Both countries see NATO — with its promise that an attack on one country is an attack on all — as the best way to ensure their security.

Finland joins, but Turkey holds up Sweden's bid

Finland became the alliance's 31st member in April, instantly doubling the size of NATO's border with Russia.

Sweden remains on the outside, however, largely due to Turkey.
 

Turkey has said Sweden harbours militants from the banned Kurdistan Workers Party (PKK), which took up arms against the Turkish state in 1984. The PKK is designated a terrorist group in Turkey, Sweden, the United States, Europe and Canada.

Turkey demanded Sweden take a tougher line against the PKK and another group it blames for a 2016 coup attempt.

In response, Sweden introduced an anti-terrorism bill that makes membership of a terrorist organization illegal, while also lifting arms export restrictions on Turkey. It says it has upheld its part of a deal signed last year.

Turkey wants other concessions, including from Canada

Turkish President Recep Tayyip Erdogan this week tied Sweden's NATO membership to actions it wants from the U.S. and Canadian governments.

Erdogan wants the U.S. Congress to approve the sale of U.S. F-16 fighter jets — and Canada to lift an arms embargo.

"Positive developments from the United States regarding the F-16 issue and Canada keeping its promises will accelerate our parliament's positive view on [Sweden's membership,]" Erdogan said. "All of these are linked."

Canada quietly agreed to reopen talks with Turkey on lifting export controls on drone parts, including optical equipment, after Erdogan signalled in July that Sweden would get the green light from Ankara, Reuters reported.

Canada suspended the export of some drone technology to Turkey in 2020 after concluding the equipment had been used by Azerbaijan's forces fighting Armenia in the enclave of Nagorno-Karabakh.

The Netherlands also previously lifted restrictions on arms deliveries to Turkey.

What comes next?

Erdogan submitted a protocol on Sweden's admission to parliament in October, but the ratification process stalled. At a NATO meeting in Brussels in late November, Swedish and U.S. officials said respectively that they had been told Turkey would ratify "within weeks" and by the end of the year.

Whether or not Sweden joins, Putin has already shown with Finland's membership that he sees NATO's expansion as a further provocation.

Finland closed its land border with Russia after seeing an unusually large number of migrants arrive there in November. Finland's foreign minister called it "hybrid warfare," accusing Russia of retaliating against Finland joining NATO by using migrants to cause internal divisions in the country.

Putin has vowed to build up military units near the Russian-Finnish border. The Kremlin leader declared, without giving details, that Helsinki's NATO accession would create "problems" for them.
