MILWAUKEE (AP) — The third day of the Republican National Convention begins Wednesday with emphasis from Republicans — led by newly nominated figures Donald Trump and JD Vance — on national security and foreign policy.

Republicans intend to critique President Joe Biden's management of crises in Europe and the Middle East. Former Trump administration officials, such as Richard Grenell, former acting director of national intelligence, and former Secretary of State Mike Pompeo, are slated to deliver speeches outlining their vision for foreign policy under a potential second Trump term.

Despite rising to prominence with his memoir “Hillbilly Elegy,” 39-year-old Ohio senator JD Vance remains unfamiliar to many Americans and even some top Republicans in Milwaukee. His address on Wednesday will introduce him to a national audience, where he will discuss his family — including his wife, Usha, and their three children — and his endorsement of Trump's policies.

Vance secured the vice presidential nomination over contenders like North Dakota Gov. Doug Burgum and Sen. Marco Rubio of Florida. His close relationship with Trump, built over years of regular phone conversations, has been underscored by Trump’s admiration for Vance’s resemblance to a young Abraham Lincoln.

Wednesday’s speeches will predominantly critique the Biden administration’s handling of global issues, including the disorderly U.S. withdrawal from Afghanistan and the ongoing Israel-Hamas conflict. The overarching theme, as stated by Trump’s campaign and the Republican National Committee, is “Make America Strong Once Again.”

“Under Joe Biden, the weakest commander-in-chief in our country’s history, America has become a global laughingstock,” the committee asserted in a pre-release statement.

Foreign policy remains a cornerstone of the Republican campaign strategy, with the party asserting that America's global stature was stronger under Trump despite a trend towards isolationism.

Grenell, former ambassador to Germany, emphasized this point during a Monday roundtable with reporters, noting, “Countries around the world are uncomfortable with the unpredictability of Donald Trump. And when I say uncomfortable, that means they don’t know exactly what he’s going to do next. And that’s a positive for us.”

While the day’s focus is set beyond U.S. borders, Republicans are expected to reiterate concerns over Biden’s perceived weaknesses on immigration, arguing that these shortcomings also compromise America's global standing. Recent claims have highlighted arrests on U.S. soil of individuals from Tajikistan with alleged ties to the Islamic State group, reinforcing Republican assertions.

The RNC has not yet released the full schedule for the day, with organizers expected to announce speakers later Wednesday morning.
