“It’s going to provide some clarity, and it’s going to leave a mark,” one of the people said.

Administration officials declined to preview the specifics, but said the speech would outline Trump’s world view, and press secretary Karoline Leavitt said Monday that the speech would emphasize “American strength.” The president has often used forums like this to denounce the Biden administration and tout his role in negotiating for peace.

Trump’s strategy to announce big deals first and seek details later has found more success where his team has taken over dormant or stagnant diplomatic processes already underway — such as with Armenia and Azerbaijan and the Democratic Republic of Congo and Rwanda.

But it has come up short in the two major conflicts he pledged to solve immediately once in office, the Russia-Ukraine war and the Israel-Hamas war.

That doesn’t seem to bother Trump much, and he has relished opportunities to promote himself as a peacemaker. He often gloats about the “seven wars” he has stopped, and the many “good friends” he has around the world, even in countries he is punishing with unprecedentedly high tariffs.

“This is a man who seeks a Nobel [Peace] Prize for the various efforts that he has undertaken, and I would expect him, maybe not necessarily, to lobby directly in front of the U.N. General Assembly for that recognition, but I think to reinforce the brand that I think he has evolved into, which is that of a peacemaker in certain theaters,” said Jonathan Schanzer, the executive director of the Federation for Defense of Democracies, a non-partisan Washington think tank.

Despite his improved personal relationships with several leaders, especially in Europe, Trump’s more unrestrained and ambitious agenda has frayed ties with several long-time allies, most of all India, which he’s hit with high tariffs.

His bellicosity — an expressed desire to conquer new territory, from Greenland to the Panama Canal, and a clear willingness to unleash military force, be it by bombing nuclear development sites in Iran or shooting suspected Venezuelan drug boats out of the water — has rattled allies and adversaries alike.
