Donald Trump is zeroing in on national security, foreign policy and America’s military.

During a speech in Philadelphia, the Republican blasted his rival Hillary Clinton — describing her record as “disqualifying.”

“In a Trump administration, our actions in the Middle East will be tempered by realism,” Trump stated, explaining that regime change produces radical terrorism. During his remarks at the Union League of Philadelphia he added, “we can make new friends, rebuild old alliances and bring new allies into the fold. I’m proud to have the support of war fighting generals.”

The Union League of Philadelphia has roughly 3,000 members, according to the Associated Press, and began in 1862 in support of President Abraham Lincoln and the Union.

Trump blasted his rival’s record as secretary of state on foreign policy and national security, saying he will be guided by “diplomacy, not destruction.”

“She’s trigger happy and very unstable,” the New Yorker stated of Clinton, also calling her “reckless” over her use of a personal server with classified emails during her time as secretary of state.

Trump criticized Clinton’s handling of Libya, Syria, ISIS and Iran. “What have we gotten from the horrible decisions made from President Obama and Secretary Clinton?” Trump questioned.

An NBC News|SurveyMonkey Weekly Election Tracking poll published early Wednesday showed that voters who currently serve in the military or previously served prefer Trump over Clinton by 19 points.

The Republican nominee laid out several proposals in a campaign press release ahead of his speech about how to “update and upgrade” the U.S. military.

The press release lists Trump’s 10 proposals:

PROPOSAL: Immediately after taking office, Mr. Trump will ask the generals to present a plan within 30 days to defeat and destroy ISIS. PROPOSAL: Mr. Trump will ask Congress to fully eliminate the defense sequester and will submit a new budget to rebuild our military as soon as he assumes office. PROPOSAL: Mr. Trump will build an active Army of around 540,000, as the Army’s chief of staff has said he needs.

PROPOSAL: Mr. Trump will build a Navy approaching 350 surface ships and submarines, as recommended by the bipartisan National Defense Panel.
