WASHINGTON — Secretary of State Mike Pompeo will outline a new strategy on Monday for constraining Iran, centered around a demand that the United States’ European allies have already rejected: that Tehran enter negotiations in a new deal that would permanently ban Iran from any substantive manufacturing of nuclear fuel and, in turn, forever cut off a pathway to building a bomb.

Mr. Pompeo is expected to call for broadening the number of countries engaging in the talks, perhaps hoping to pick up help from other nations, like Japan and Arab states, that were not involved in negotiating the 2015 deal with Iran that President Trump pulled out of about 10 days ago.

But the negotiating strategy of the United States’ new chief diplomat is unlikely to be embraced by major European powers, who opposed Mr. Trump’s move and are talking now about how to nullify the effects of threatened United States sanctions on European firms that do business with Iran.

The core of the opposition has been from the European Union, whose leader of the heads of government, Donald Tusk, issued a stinging Twitter post this week about Mr. Trump. “With friends like that who needs enemies,” Mr. Tusk tweeted. “We realise that if you need a helping hand, you will find one at the end of your arm.”
