Russia’s espionage apparatus in the West is huge, as the scale of the expulsions indicates. Including an earlier action by Britain, some 135 Russian officials have been ordered out of 21 countries in response to the March 4 attack on Sergei Skripal and his adult daughter, Yulia. This could deal a temporary blow to Russian intelligence services.
However, Russia’s malign operations in the West extend far beyond the agents it dispatches under diplomatic cover. It has an army of hackers and trolls operating online, many of whom have been busy attempting to sow confusion about responsibility for the use of the nerve agent. Mr. Putin depends on a network of government ministers and business owners to fund these operations and others — like the paramilitary force that recently attacked U.S. troops in Syria. That is the real foundation of his regime, and so far it has barely been touched.
Both the British government and the Trump administration have potentially potent leverage. Many Russian oligarchs and some senior government officials have millions invested in the London property market. The government of Theresa May has legal authorities it could use to target some of those assets, but it has not yet done so. Similarly, Congress passed legislation last year mandating the creation of a list of oligarchs and officials close to Mr. Putin who could be subject to asset freezes and visa bans. The administration grudgingly produced the list but has yet to act, apart from the recent designation of a handful of officials and Internet hackers, most of whom were already under indictment or sanction.
Both governments, as well as European Union officials, are promising further action, and we hope that it is forthcoming. But there is reason for concern, given the substantial support Mr. Putin continues to enjoy from several E.U. governments and the curious behavior of Mr. Trump, who seemingly cannot bring himself to criticize the Russian leader. When Mr. Trump called Mr. Putin last week, he ignored the advice of his advisers and did not mention the nerve-gas attack. Instead he promised to meet Mr. Putin soon and embraced his priority of arms-control negotiations. Then he took to Twitter to argue, again, that “getting along with Russia (and others) is a good thing.”
Getting along would be good, on the right terms. But it’s not feasible as long as the Kremlin is dedicated to disrupting Western governments and elections, subjugating neighbors such as Ukraine, and murdering its opponents in Western cities using banned chemical agents. Mr. Putin must be deterred. Expelling a few dozen of his spies is a step, but it’s not likely to suffice.
