Donald Trump’s flurry of offhand remarks and abrupt zingers on Russia -” praising Vladimir Putin, dismissing NATO – have jolted the world, not to mention the U.S. presidential campaign.

With Russia’s behavior rattling nerves in the U.S. and abroad, the Republican presidential nominee is accused of cozying up to a “dictator.” Of threatening the very underpinnings of America’s relationship with Europe. And of naivete.

Yet for all that, Trump’s words are consistent with some long-held U.S. views, many experts say. The idea of fostering U.S.-Russian cooperation isn’t outlandish — after all, Hillary Clinton tried to “reset” relations with Russia as secretary of state. And past U.S. administrations of both parties have quietly complained that other NATO members should pay their share to the alliance.

It’s really Trump’s way of expressing his views that has shocked many foreign policy experts.

On Wednesday, Trump offered this vision for rosier U.S.-Russian relations:

“I would treat Vladimir Putin firmly but there’s nothing that I can think of that I’d rather do than have Russia friendly — as opposed to the way they are right now — so that we can go and knock out ISIS together along with other people and with other countries,” he said. “Wouldn’t it be nice if we actually got along with people?”

Trump also praised the Russian president for having “better leadership qualities” than President Barack Obama and indicated he’d consider lifting sanctions against Moscow and recognizing Russia’s annexation of Crimea.

As for NATO, Trump said the basic idea of the alliance was OK but that “it’s got to be modernized. And countries that we’re protecting have to pay what they’re supposed to be paying.”

Days earlier, he suggested that he would decide whether to protect NATO allies against Russian aggression based on whether they had “fulfilled their obligations” financially.

And his offhand invitation for Russia to help unearth the deleted emails from Clinton’s State Department years appeared to violate a cardinal rule against foreign meddling in U.S. politics.

Foreign policy experts of all stripes “are left slack-jawed” by Trump’s pronouncements, said Derek Chollet, a senior adviser at the German Marshall Fund and former Pentagon official in the Obama administration.

“He looks at the world solely through the prism of business transactions, talking about allies as if they’re Atlantic City contractors that he can bilk,” said Chollet, who spoke out in favor of Clinton during her Democratic primary campaign against Sen. Bernie Sanders.

But Steven Cohen, professor emeritus of Russian studies at Princeton and New York University, credits Trump for homing in on issues that are ripe for discussion. He said that while Trump talks “elliptically” and “just can’t wonk,” the GOP nominee “in his own way seems to be advocating detente,” which Cohen sees as an admirable goal.

Cohen said it’s time for critics to stop using “McCarthyite” language to demonize Trump and have a serious discussion about the issues he’s raising.

“It’s called a debate,” said Cohen. “You’re supposed to have them in a presidential campaign.”

And yet Democrats are not the only ones to recoil at Trump’s remarks. Senate Majority Leader Mitch McConnell, among other top Republicans, swiftly expressed disagreement with the nominee and promised that other NATO members can count on the U.S. to defend them.

David Kramer, who was a State Department official in the George W. Bush administration, said he and many other foreign policy thinkers see “a Russia that poses a threat. He (Trump) sees a leader in Vladimir Putin who he thinks he can develop a good relationship with.”

Trump’s comment about Crimea and Russian sanctions, says Kramer, sent “terrible signals and will be interpreted not only as a betrayal by the United States of our allies but as rewarding aggressive behavior by Russia.”

In the 2012 presidential campaign, the dynamic over Russia was switched: Republican nominee Mitt Romney then criticized Obama for being too accommodating toward Russia. And Democrats were the ones faulting Romney for saying that Russia was America’s “No. 1 geopolitical foe.”

Obama’s early hope for that reset with Moscow had largely evaporated even before Russia’s 2014 annexation of Ukraine’s Crimean peninsula and its military intervention in eastern Ukraine, which unnerved countries on NATO’s eastern flank that fear they also may be targets of Russian intimidation or aggression.

Against that backdrop, Trump’s remarks raising doubts about honoring U.S. NATO commitments created an international uproar.

Julianne Smith, a former deputy national security adviser to Vice President Joe Biden, said Trump doesn’t seem to grasp the complexities of the U.S. relationship with Russia, reflecting both inexperience and a lack of strong advisers.

“It’s not a question of whether Putin is good or bad,” she said. “It’s about handling a very delicate and volatile situation that can go sour very quickly.”

Yet others note that even the current Obama administration depends on Russia and seeks its help with many world crises.

In Syria, despite deep mutual frustration, the U.S. and Russia are trying to work together to end a five-year civil war that has led to global terrorism fears. They’re even discussing a military alliance against the Islamic State group. Cooperation extends to the Iran nuclear deal, North Korea and more.
