Putins brutal attack on Ukraine has helped revive the West, but the homegrown threats to liberal democracy fester under a veneer of solidarity -…

WASHINGTON (Project Syndicate) The solidarity on display at the recentNATO,U.S.-EU, andG-7summits has revealed a rejuvenated West. While Russian President Vladimir Putin continues to wage war on Ukraine, the Atlantic democracies are responding with impressiveand somewhat unexpectedunity as they arm Ukraine, reinforce NATOs eastern flank, and sanction the Russian economy.

Instead of turning away migrants, European Union member states are opening their doors to millions of Ukrainian refugees. The U.S. Congress seems to have rediscovered the bipartisan comity that has long been missing in Washington.

Prolonged economic insecurity and yawning inequality have depopulated the political center.

The political theoristFrancis Fukuyamaevenforeseesa new birth of freedom that will get us out of our funk about the declining state of global democracy, adding hopefully that the spirit of 1989 will live on, thanks to a bunch of brave Ukrainians.

Not so fast. The political ills plaguing the Atlantic democracies may be out of the headlines, but they have not gone away. While Russias invasion is certainly a wake-up call for the West, the prospect of a new cold war will not by itself cure the United States and Europe of illiberalism and political dysfunction.

In fact, the war in Ukraine will likely have economic spillover effects that foster political blowback. Accordingly, both America and Europe need to keep focusing on getting their own houses in order even while ensuring that the tragedy in Ukraine receives the resources and attention it deserves.

In Cold War America, the political discipline engendered by the Soviet threat did help mute partisan conflict over foreign policy. Similarly, the prospect today of a new era of militarized rivalry with Russia isreviving bipartisan centrismon matters of statecraft.

Although the neo-isolationist wing of the Republican Party in Congress may be relatively quiet for now, it enjoys strong support among the party base and is likely to reassert itself as Western-led sanctions against Russia hurt U.S. consumers.

The left wing of the Democratic Party is no longer clamoring for cuts to the defense budget and a fast and deep pullback from fossil fuels. Both the hawkish and the neo-isolationist wings of the Republican Party have toned down their criticism of President Joe Biden and generally rallied behind his response to the Russian invasion.

But this return to bipartisanship is likely to be short-lived.

The bipartisanship of the Cold War era rested not just on the Soviet threat, but also on the ideological centrism sustained by widely shared prosperity within America. Yet prolonged economic insecurity and yawning inequality have since depopulated the political center, and ideological moderation has given way to bitter polarization.

This erosion of the political center explains the rapid evaporation of the surge in bipartisanship that followed the Sept. 11, 2001, terrorist attacks. And it explains why, just before the war in Ukraine captured the countrys attention, public intellectuals in the U. S weredebatingthe prospects for civil war. According to a poll conducted late last year,64% of Americansfear that U. S democracy is in crisis and at risk of failing.

Thehighest U.S. inflation rate in 40 yearsis currently heightening the risk of a return to the illiberal politics of grievance. The rising cost of energy and food is one of the main reasons why Bidensapproval ratingshave remained low despite his strong handling of the war in Ukraine.

As the November midterm elections near, scant Republican support for Biden will translate into renewed partisan rivalry. And although the neo-isolationist wing of the Republican Party in Congress may be relatively quiet for now, it enjoys strong support among the party base and is likely to reassert itself as Western-led sanctions against Russia hurt U.S. consumers.

Given the potential for illiberal populism to make a comeback in the U.S., the Biden administration urgently needs to continue advancing its domestic agenda. Investing in infrastructure, education, technology, health care, and other domestic programs offers the best way to alleviate the electorates discontent andrevivethe countrys ailing political center. Thebudgetthat Biden proposed this week is a step in the right direction.

Europe, too, should keep a close eye on its home front as it focuses on its response to Ukraine war. While Europes political center has remained stronger than Americas, and the EU has shown impressive unity in the face of Russian aggression, strains to European cohesion lurk just beneath the surface.

Europes magnanimous welcome to Ukrainian refugees may triggerdomestic backlashesas costs mount and the prospect of permanent resettlement looms. Weaning the EU off Russian fossil fuels will require considerable investment and could lead to even higher energy prices, potentially hampering Europes economic recovery from the COVID-19 pandemic.

And while Poland and Hungary are now front line states that deserve allied support, both are still ruled by illiberal governments that threaten core European values; they should not be let off the hook.

Europeans, like Americans, need to continue working hard on domestic renewal. Economic restructuring and investment, reform of immigration policy and border control, and more pooling of sovereignty on foreign and defense policy can all help consolidate the EUs solidarity and democratic legitimacy.

Putins brutal attack on Ukraine has helped revive the West. But the homegrown threats to liberal democracy that were front and center before the war still require urgent attention, even amid the strenuous effort to defeat Russias attempt to subjugate its neighbor.

It would be tragically ironic if the West succeeds in turning Putins gamble in Ukraine into a resounding defeat, only to see liberal democracies then succumb to the enemy within.
