Now, with President Trump in the White House, Kashriel thinks it may just happen.
His settlement is approximately four miles east of Jerusalem in the occupied West Bank. Most of the international community considers its construction to be illegal, built on land captured during the 1967 war.
Still, it has steadily grown from what began as a cluster of prefabricated buildings erected by 23 families in the 1970s into a burgeoning satellite city of Jerusalem. Palm trees line the wide roads of what looks like a Florida suburb. Red-roofed houses and high-rises are home to 42,000 people, who are served by all of the accouterments of a modern city: schools, restaurants, cafes and a shopping mall.
Expansion here is particularly contentious because it could cut off Arab areas of East Jerusalem from other Palestinian territory and hobble the creation of a viable Palestinian state. Still, Maale Adumim keeps growing. In the industrial park on its outskirts, already home to 360 businesses, ground has just been broken on "Design City," a nearly 600,000-square-foot, 160-outlet interior-design retail mall.
While previous U.S. administrations called settlements an obstacle to the peace process, the Trump administration has been more restrained in publicly criticizing them, a clear break from the frequent censure under President Barack Obama of Israeli settlement activity.[Israelis voice warnings, Palestinians talk of ‘blackmail’ after Trump tweets]
Emboldened by a more supportive White House, Israeli leaders have proposed a flurry of bills and proclamations that seek to annex areas of the West Bank and re-engineer Jerusalem's demographic balance by redrawing the city's map to exclude Arab neighborhoods and include Israeli settlements.
Last year, Israeli lawmakers introduced legislation, called the Greater Jerusalem bill, that would expand the city's municipal boundaries to include 19 settlements, including Maale Adumim. For the moment the bill has stalled, not yet making it to a vote in the Knesset, Israel's parliament. But other efforts are underway.
Betty Herschman, advocacy director at Ir Amim, which monitors developments in Jerusalem as they relate to the peace process, said Israel has seen a "groundswell of unilateral proposals."
On New Year's Eve, the central committee of Prime Minister Benjamin Netanyahu's ruling Likud party adopted a nonbinding resolution proposing annexation of all West Bank settlements to Israel and allowing unfettered construction.
The prime minister was not present at the gathering, but Public Security Minister Gilad Erdan told the crowd that Trump's presidency presents a "historic opportunity."
"Today we have a president in the White House who says explicitly, yes, he understands that the obstacle to peace is Palestinian incitement, not settlement in Judea and Samaria," he said, employing the names that some Israelis use to refer to the West Bank. "We must not miss this opportunity."
Some political observers see the Likud action as motivated by domestic politics, a populist move as Israeli elections approach.
But Hagai El-Ad, the director of the Israeli human rights group B'Tselem, said there is a battle underway between those who want to continue "smart occupation," which manages to "fly two inches below international outrage" while incrementally shifting facts on the ground, and those who advocate "dumb occupation" — moving forward with formal annexation.
Trump's presidency has given new vigor to the latter, he said.[White House vows to stand firm on Trump’s recognition of Jerusalem as Israel’s capital]
Trump's recognition of Jerusalem as Israel's capital, in particular, was taken by Israelis and Palestinians as an endorsement of Israel's policies.
"They've been encouraged by the current administration, especially after the resolution on Jerusalem," said Hanan Ashrawi, a member of the Palestine Liberation Organization's executive committee. "They feel like they have a free hand now. We are at a very, very critical juncture."
In his office in Maale Adumim, Kashriel says the change of attitude toward settlements under the Trump administration was immediately apparent.
All previous U.S. administrations had largely shunned the settler community, he said. "They boycotted us. They never wanted to meet us," he said.
But Kashriel was invited to Trump's inauguration in Washington. "I think they wanted to show us there is a change in the atmosphere in Washington," he said. That was followed by an invitation to Fourth of July celebrations at the U.S. ambassador's residence north of Tel Aviv.
Trump's son-in-law, Jared Kushner, and his family are longtime supporters of Israeli settlements in the West Bank, as is Trump's ambassador to Israel, David M. Friedman.
"So you see that there is change," Kashriel said. "This is the reason now that the Knesset members are all the time raising these resolutions."[T rump threatens to cut off U.S. aid to Palestinians over Jerusalem row]
"The most important goal is to strengthen the Jewish majority in Jerusalem," said Intelligence Minister Israel Katz, who wrote the text of the Greater Jerusalem bill.
The bill would incorporate Jewish settlements into the city. Jerusalem Affairs Minister Zeev Elkin, who supports the legislation, has made a further proposal. He would like boundaries of the city's municipality redrawn to split off Arab areas of East Jerusalem that are separated from the rest of the city by Israel's separation barrier, while keeping them as part of the state.
A vote in the Knesset this month made that prospect possible while also raising the number of lawmakers who would be needed to support a proposal to give up Israeli sovereignty over any part of the city.
Areas outside the security wall already have become virtually lawless. Further, although they are legally part of Jerusalem, the municipality no longer provides basic services, citing security reasons. But these neighborhoods are not under the control of the Palestinian Authority, either.
Israeli authorities have turned a blind eye to unabated Arab construction in those neighborhoods, compared with tight restrictions on building permits in Arab areas inside the wall.
Munir Zagheir, a community representative for Kafr Aqab, one of the areas Elkin suggests removing from the municipality, says there has been a long-term effort to pull Palestinians out of central Jerusalem and "empty Arabs to the sides."
About a mile from Kashriel's office, 58 Arab Bedouin families live in a ramshackle collection of tents and shacks called Jabal al-Baba. Attalah Jahleen, their 42-year-old representative, said the community's fortunes have deteriorated over the past year.
"Before Trump took office, the American consulate used to visit us on a regular basis," he said. "Since Trump took over, nothing."
The U.S. Consulate in Jerusalem said its staff "continues to speak with a wide variety of contacts in Jerusalem, the West Bank and Gaza."
The families received eviction orders late last year, and there have been dozens of demolition orders, with Israeli authorities attempting to resettle them elsewhere.
Trump administration officials, Jahleen said, "have given up on us."
