Israeli Prime Minister Benjamin Netanyahu pledged Tuesday to annex all Jewish settlements in Judea and Samaria, beginning with the Jordan Valley, if he is reelected.

The prime minister vowed to work with President Trump’s administration to extend Israeli sovereignty, The Jerusalem Post reported. He said he plans to coordinate with the U.S. president after he announces his Middle East peace plan the day after the Israeli election on Sept. 17.

“This is an historic opportunity that we may not have again,” Netanyahu said in his statement he delivered Tuesday.

The Jordan Valley and other Jewish settlements that Netanyahu pledges to annex make up about 30 percent of the West Bank, of which Israel and Palestine both claim ownership, according to Newsweek.

The prime minister warned against voting for his opponents, Blue and White leaders Benny Gantz and Yair Lapid, alleging they support giving up the Jordan Valley. The Jerusalem Post reported that Gantz and Lapid have said they intend to keep the valley, if elected.

“The Israeli voter will be asked to pick between those who defend the security borders of the state of Israel, and those who support giving over lands and uprooting hundreds of thousands of Jews from their homes and lands,” Netanyahu said in his statement.
