Visiting New Hampshire to again bash free-trade deals as job killers, Donald Trump conducted a brief town hall Thursday in which he defended Israel and said he would look into a woman's suggestion that airport security screeners be replaced with veterans.

The woman protested Transportation Security Administration guards who wear "hibby jobbies" at airports — an apparent reference to Muslims — as she asked the Republican presidential candidate to have veterans do TSA jobs.

"We're looking at that," Trump said during the appearance in Manchester, N.H. "We're looking at a lot of things."

Trump has vowed to tighten the nation's borders, in part to stop "radical Islamic extremists" from entering.

Another man protested American military involvement in the Middle East "on behalf of Zionist Israel," prompting a defense of the Jewish state from Trump.

"Israel is a very, very important ally of the United States," the New York businessman said. "And we are going to protect them 100%"

Trump added, "that was a tough question on Israel — that was nasty!"

Before taking a half-dozen questions, Trump spoke about free trade, globalism and jobs during an appearance at a shuttered Sylvania business in Manchester.

"It's very sad when you look at a plant like this," Trump said in arguing that free trade agreements have sent U.S. jobs overseas and that competitors like China and Mexico are violating the rules.

Trump also again pledged to kill the proposed Trans-Pacific Partnership with Asian nations and to re-write or withdraw the U.S. from the North American Free Trade Agreement with Mexico and Canada — and also cracked a joke about Mexican intentions as a plane buzzed overhead.

"That could be a Mexican plane up there," Trump said. "They're getting ready to attack."
