As President Trump pushes a new plan to take control of Gaza and clear out an area that once was home to an estimated two million residents, he is advocating bringing the United States much more deeply into a region where his family has a growing collection of real-estate and business interests.

There is no part of the world as crucial to the growth of various Trump family business ventures as the Middle East, including Saudi Arabia, Qatar, United Arab Emirates and Israel, when the full portfolio of Mr. Trump as well as Jared Kushner, his son-in-law, are included. Here is a look at the family’s interests in the region and Mr. Trump’s proposal for Gaza.

What Trump proposed for Gaza

Mr. Trump declared on Tuesday that the United States should seize control of Gaza and permanently displace the entire Palestinian population of the devastated seaside enclave.

Mr. Trump suggested the resettlement of Palestinians would be akin to the New York real estate projects he built his career on. “If we could find the right piece of land, or numerous pieces of land, and build them some really nice places with plenty of money in the area, that’s for sure,” he said. “I think that would be a lot better than going back to Gaza.”

“Everybody I’ve spoken to loves the idea of the United States owning that piece of land,” Mr. Trump added, “developing and creating thousands of jobs with something that will be magnificent.”

Mr. Trump’s aides on Wednesday walked back some of his comments, with the White House press secretary, Karoline Leavitt, saying that “the president has not committed to putting boots on the ground in Gaza.”
