itself that may feed the next wave of global terrorism should hateful ideologies like white supremacy continue to flourish within its borders.

"Agency lawyers maybe would stroke at the lines between free speech, political activity, and the international terrorism activity," the former official told Newsweek.

"[The Capitol riot] was a shock for everyone, for the American audience, of course, but it was a shock for the whole world," one European official who spoke on the condition of anonymity told Newsweek.

The European official emphasized the nuances of white nationalism as it exists in the U.S.

"White supremacist violent movements are less important in Europe than in the U.S., and the internationalization of such movements is always hard because they heavily rely on strong national issues," the European official said.

A German official told Newsweek that Germany has numerous prevention programs in place, including in schools, on local levels, on state levels and on the federal level, and that these programs "also address threats from abroad, which is not totally new, since extremist ideologies spread via the internet.".

"Over the past decade, we have seen surging violence in the United States, Europe and beyond motivated by elements of white supremacy," Anti-Defamation League CEO Jonathan Greenblatt told Newsweek.

Others spreading exporting their controversial creed include white nationalist Counter Currents editor-in-chief Greg Johnson, Occidental Observer editor Kevin MacDonald, alt-right leader Richard Spencer and European New Right proponent Tomislav Sunić, according to the ADL.

"Global access to white supremacist ideology, and its easy dissemination across borders via various social media platforms," Greenblatt said, "means many of the ideas promoted by the white supremacist movement—curtailing of non-white immigration, attacks on globalization and the accompanying conspiracies about elitist globalists—are increasingly part of mainstream political and social rhetoric.".

"For years, my team and I have been warning about the growing connections between U.S.-based extremists and white supremacists operating abroad," Soufan told Newsweek

While he said high-profile attacks such as those in Norway and New Zealand "invited closer scrutiny on global white supremacy extremism," he said that such scrutiny "reveals that, like the global jihadist movement, violent white supremacists and far-right actors maintain international linkages and continue to forge global networks with ideologues radicalizing individuals across the globe."

He compared jihadi hubs like Afghanistan, Iraq and Syria to white nationalist recruitment hotspots like Ukraine, where far-right militias are involved on both sides of a U.S.-supported war against rebels aligned with Russia, whose own ultranationalist Russian Imperial Movement became the first white nationalist group to be designated by the State Department as a foreign terrorist organization earlier this month

"We tend to use language like 'domestic' terrorism when talking about white supremacy extremist groups, which leads people to believe this threat is strictly a national issue
