BUDAPEST — Prime Minister Viktor Orban of Hungary has fiercely resisted a proposed European embargo of Russian oil, saying it will drop an “atomic bomb” on his nation’s economic system. One other potential casualty of such a ban: the gravy practice for tradition warriors in Europe and in the US fueled by Hungary’s earnings from Russian crude.

Gorged with money due to low-cost provides of Russian oil and fuel, the Hungarian power conglomerate MOL — one of many Central European nation’s largest and most worthwhile corporations — final month introduced it will pay dividends of $652 million to its shareholders.

Greater than $65 million of that can go to a privately managed training basis that final yr hosted the Fox News host Tucker Carlson at a competition of right-wing pundits in Hungary. It has additionally supplied stipends and fellowships to conservative People and Europeans in search of a secure haven from what they bemoan because the unfold of “cancel tradition” again residence.

A few of them featured this week on the first Hungarian version of the Conservative Political Motion Convention, or CPAC, a gathering of the suitable wing of American politics. The occasion, attended by Mr. Orban, opened in Budapest on Thursday below the slogan “God, Homeland, Household.”

Hungary has for years served as a beacon for foreign conservatives who admire Mr. Orban’s hostility to immigrants, L.G.B.T.Q. rights, George Soros and liberals normally. Russia’s invasion of Ukraine, nevertheless, has put extreme pressure on that position, stirring anger amongst some conservatives about Mr. Orban’s cozying as much as the Kremlin.

It has additionally threatened to pressure Mr. Orban’s pact with voters, who gave his Fidesz occasion a landslide victory in elections final month on the promise that, due to low-cost power from Russia, gas and utility prices wouldn’t skyrocket as has occurred elsewhere in Europe.

A gradual provide of Russian power has turn out to be such a central a part of Mr. Orban’s financial and political mannequin that ending it “is a pink line for him,” mentioned Andras Biro-Nagy, founder and director of Coverage Options, a Budapest analysis group. “Russian oil and fuel are completely very important to his complete scheme.”

This dependence has alarmed even a few of his overseas followers who’ve taken up paid positions at Mathias Corvinus Collegium, often called M.C.C., the training basis that advantages from MOL’s enterprise with Russia. The muse holds a ten % stake within the Hungarian power firm, which depends closely on deliveries of Russian oil to feed its important refinery southwest of Budapest and one other one it owns in Slovakia.

“I’m very sad concerning the Hungarian place vis-à-vis Russia broadly talking, and particularly about power,” mentioned Daniel Pipes, a conservative American scholar awarded a paid “senior fellowship” by the muse. “On the identical time, I’m very constructive concerning the Hungarian stance on immigration,” he mentioned. “So I’m ambivalent. I dislike the Russia coverage and I do just like the immigration coverage.”

Additionally sad is Poland, whose governing occasion, Legislation and Justice, shares Mr. Orban’s hostility to liberals however has been infuriated by his dogged resistance to efforts by the European Union to ban Russian oil, his refusal to let arms destined for Ukraine go by means of Hungary and his failure to sentence Russia’s president, Vladimir V. Putin.

Nervous that the Hungarian power firm is just too beholden to Russia, the Polish Senate handed a decision in March blocking a cope with Poland’s state-owned power firm that may have allowed MOL to accumulate greater than 400 Polish fuel stations.

Bogdan Borusewicz, the opposition senator who initiated the transfer, mentioned in an interview in Gdansk, the positioning of a giant Polish refinery, that the warfare in Ukraine had made it harmful to let a Hungarian firm depending on Russia into his nation’s market.

“You can debate about this earlier than the warfare,” he mentioned, “however now it’s inconceivable to have any illusions” concerning the loyalties of Mr. Orban, whom he described as “Putin’s most vital ally within the E.U.” For MOL, he mentioned, “cooperation with Russia is a vital a part of its enterprise and even its survival.”

MOL declined interview requests however, in public statements, has harassed the issue and expense of shifting to non-Russian oil. Its Danube Refinery, south of Budapest, invested closely over eight years to accommodate crude from different international locations, which is mostly dearer, nevertheless it nonetheless depends upon Russia for 65 % of its wants.

Reporting a giant soar in earnings, MOL warned in its annual monetary report this spring that it was uncovered to Russia by means of a minority stake in a small Russian oil firm, BaiTex, and by “the bodily circulate of crude oil by means of the transportation system in Russia and Ukraine.” That circulate, it famous, had not “so far” been restricted.

Since then, the chief arm of the European Union has sought to chop it off solely.

Doing that, mentioned Tamas Pletser, an oil and fuel analyst with Este Financial institution in Budapest, can be a extreme blow. MOL, he mentioned, has profited till now from a widening worth distinction between European Brent and the cheaper Russian crude.

“They make an extra $10 million per day on this present scenario, which relies on the Russian provide and Russia’s invasion of Ukraine,” Mr. Pletser mentioned.

Many tens of millions of {dollars} have gone to M.C.C. and two different nominally impartial foundations, which collectively maintain 30.49 % of the power firm and are its largest shareholders. The shares was once held by the state, however Mr. Orban two years in the past gifted them, together with different beneficial property, to the foundations as a part of what he mentioned was an effort to overhaul education however which critics known as legalized theft. The chairman of M.C.C. is Balazs Orban, who can also be the prime minister’s political director (although not a relation).

Zoltan Szalai, M.C.C.’s normal director, acknowledged in an interview, “This yr, MOL has been excellent to us.” The dividend cash M.C.C. acquired this yr from MOL is greater than double its annual funds.

Mr. Szalai mentioned his basis ought to have the ability to address a decline in power firm earnings if Mr. Orban loses his struggle to maintain Russian crude flowing. “We’re considering in the long run, and MOL is an excellent and severe firm,” Mr. Szalai mentioned.

On the subject of banning Russian oil, “it’s not true that Hungary doesn’t have a alternative,” mentioned Piotr Wozniak, Poland’s power minister in a earlier Legislation and Justice authorities and longtime power govt. “It won’t be low-cost or straightforward however it’s not inconceivable.”

However, he added, “The query is whether or not Hungary needs to make this alternative.”

Making that alternative notably tough is Mr. Orban’s vote-winning promise final month to maintain power costs in examine by means of government-imposed worth caps.

Shortly earlier than the Ukraine invasion, Mr. Orban traveled to Moscow to meet Mr. Putin, securing assurances that Hungary could count on supplies of Russian natural gas.

Moscow final month abruptly cut off deliveries to Poland and Bulgaria however continues to be supplying Hungary. Any suspension, both by Russia or on account of Western sanctions, would drive Hungary to purchase dearer provides in the marketplace.

Giving the keynote handle at CPAC on Thursday, Mr. Orban talked about the warfare in Ukraine, calling Russia the aggressor, however largely targeted on advising conservatives the best way to succeed politically. “The primary level,” he mentioned, “is that we should play by our personal guidelines.”

Mr. Carlson, the Fox Information host who lately mentioned that he was “rooting” for Russia in its warfare with Ukraine, despatched a quick video message of help for the convention.

The principle organizer of the occasion is the Heart for Basic Rights, a Hungarian outfit funded by the federal government that claims it’s combating to repel the “relentless assault” on “Judeo-Christian tradition, patriotism, sovereignty, the household, the created nature of man and girl and our dedication to life.”

The middle initially mentioned it was engaged on CPAC’s Budapest occasion with M.C.C. The muse, nevertheless, denied serving to to arrange CPAC, although it mentioned it supported its goals.

Mr. Szalai, the M.C.C. normal director, denied his basis pushed any political agenda, saying in an interview that its mission was to advertise “basic frequent sense.”

“To say we’re far proper just isn’t honest,” he added.

Mr. Orban’s critics say that M.C.C. has established itself as what Mr. Biro-Nagy of Coverage Options calls “one of many crown jewels of Orban’s mission to create a conservative, cultural hegemony.”

Among the many overseas tradition warriors listed by M.C.C. among the many “visitor instructors” this yr was Rod Dreher, an American author who has praised Hungary’s hard-line stance in opposition to Muslim immigrants.

Mr. Dreher mentioned he was “not within the least bothered” that M.C.C. benefited from Russian oil. He mentioned his personal pay, nevertheless, got here from one other Hungarian government-funded entity.

“I deplore Russia’s invasion, and hope Ukraine prevails, however I don’t share this horror of Russia and ties to Russia that the ruling class within the U.S. and Western Europe do,” he mentioned.
