Reaction to the Brexit vote was extremely mixed from countries on the outside of the EU, looking in.
Brexit: The latest developments, how it happened and what's next
Russia
"The overall mood in Russia can be described as malicious joy," Aleksei Makarkin of Russia's Centre for Political Technologies told the New York Times on Friday. People feel "some sort of relief that [Brits] have their problems too."
Certainly President Vladimir Putin welcomed the news. He has worked hard to undermine European solidarity, especially with EU efforts to punish Moscow for its annexation of Crimea and its support for the breakaway regions in southeastern Ukraine.
"Without Britain, there won't be anybody in the EU to defend sanctions against us so zealously," Sergey Sobyanin, the mayor of Moscow, wrote on Twitter.
Margarita Simonyan, editor-in-chief of Russia's Sputnik news service, celebrated – "Fun times begin," she posted on Twitter. "#Whereismypopcorn."
Israel
Just as Mr. Putin enjoys seeing the weakening of the EU, Israeli Prime Minister Benjamin Netanyahu must also be quietly pleased at the Brexit vote.
While Britain has been one of Israel's stronger supporters among EU members, its exit will likely make the EU less able to pursue its latest efforts at Middle East peace-making.
Since the days of the European Economic Community, the forerunner to the European Union, Europe has advocated for an end to Israeli settlement construction in the Palestinian West Bank, and for the creation of a Palestinian state. Just this week, a French initiative intended to force Israel and the Palestinian leadership back into peace talks won full EU support.
The Palestinian leadership has welcomed the initiative, but the Israeli government said it will go down in history as having "pushed peace further away."
After the British vote, however, Israel's leaders hope the EU may be more intent on dealing with its own internal matters than on putting more pressure on the Jewish state.
Turkey
Turkey takes the opposite point of view.
Long concerned with the rise of racism and Islamophobia, Turkey believed that a strong and united Europe stood the best chance of fostering inclusiveness, and of standing up to Russia's increasingly aggressive behaviour in Eastern Europe.
Britain's exit from the European Union, Turkey fears, will open the floodgates to populist parties of the right throughout Europe, increasing anti-immigrant sentiment, further destabilizing the EU and making it impossible for Turkey ever to join.
Not that Britain was ever a great champion of Turkey's bid for admission.
Throughout the Brexit campaign, many on the Leave side pointed to Turkey as the kind of threat they hoped to avoid. Turks were even more upset by the response to a racist argument given by British Prime Minister David Cameron, leader of the Remain campaign.
Mr. Cameron told people they had nothing to fear from Turkish membership because it wouldn't happen before "the year 3000."
The Balkans
Leaders of the six Balkan states – Montenegro, Serbia, Bosnia-Herzegovina, Kosovo, Macedonia and Albania – lined up as prospective EU members now fear that Britain's exit will kill any chance these countries had for admission.
For one thing, Brussels will be preoccupied for at least the next two years with severing its relationship with Britain rather than considering applications for accession from the Balkan states.
For another, membership in an increasingly xenophobic EU no longer holds the same allure, says Denisa Kostovicova, a Balkans specialist at the London School of Economics and Political Science.
Indeed, countries in the region will be looking for an alternative future, perhaps aligned with Russia.
"The UK's referendum result was music to the ears of the region's anti-Europeanists and pro-Russianists," she said.
