MILWAUKEE (AP)–As President Donald Trump rallied supporters Tuesday night by defending his decision to kill a top Iranian general, the Democrats vying to replace him used their final debate before primary voting begins to argue that doing so made the country less safe.

With Trump firing up thousands in the battleground state of Wisconsin and the Democratic candidates squaring off in Iowa ahead of its Feb. 3 caucuses, the political events were expected to offer very different visions for the country’s future. But the contrast on Iran in nearly real time was especially stark.

Trump spent much of his speech defending his decision to order the strike that killed top Iranian General Qassem Soleimani, whom he labeled the “world’s No. 1 terrorist.” That move came under intense criticism from Democrats who said the president should have consulted Congress and raised questions about whether it really prevented an imminent attack, as some Trump administration officials have claimed.

“The Democrats are outraged that we killed this terrorist monster, even though this monster was behind hundreds and hundreds of deaths,” Trump told the crowd in downtown Milwaukee –î not far from where Democrats will hold their convention this summer. He added that Soleimani was “the king of the roadside bomb. Great percentages of people don’t have legs right now and arms because of this son of a bitch.”

The president also said Democrats “are doing everything possible to disparage what we did with the hit on this monster” and that the other party “should be outraged by Soleimani’s evil crimes, not the decision to end his wretched life.”

Moments later in neighboring Iowa, Sen. Bernie Sanders of Vermont said he feared that Trump’s actions in Iran could lead the United States into a foreign policy quagmire of the highest level.

Pete Buttigieg, the former mayor of South Bend, Indiana, said Trump had campaigned on stopping “endless wars” only to bring the country closer to them. And former Vice President Joe Biden said Soleimani’s killing was dangerous and would not have been necessary if Trump hadn’t pulled the U.S. out of a successful nuclear deal that the Obama administration had reached with Iran.

Trump also took on the leading Democratic candidates directly, saying of Sanders: “Bernie and the radical left cannot protect your family, nor can they protect our country.”

Winning back Wisconsin is a key part of Democrats’ 2020 strategy — and one of the reasons the party chose Milwaukee to host its national convention in July. Trump won the state by fewer than 23,000 votes in 2016 and he is expected to make frequent visits in the coming months as he works to maintain his edge.

Trump also went on an extended riff about his efforts to roll back energy- and water-saving regulations, panning energy-efficient light bulbs and low water flow dishwashers, showers and toilets, which he promised to replace.

“Your dishes are going to be beautiful,” he promised.

Highlighting the politics of the city, Trump’s rally was interrupted several times by protesters, who also demonstrated outside the arena where he spoke.
