Trump Keeps Saying He Will Build ‘the Greatest Dome Ever.’ Republican Senators Don’t Know What He Means.

“We’ve got an ocean on each side and Mexico and we’re supposed to have friends on either side,” one Republican senator said.

Former President Donald Trump has a new talking point: he wants Israel’s Iron Dome — its state-of-the-art missile defense shield — for the United States.

“We’re giving billions of dollars to other countries so they can build a dome,” Trump said on the campaign trail this month. “But we don’t have a dome ourselves. We’re going to have the greatest dome ever.”

In Congress, the Republicans who would have to fund such a project say they’re all for beefing up the U.S.’s missile defense systems — but they’re not quite sure what Trump is really asking for.
