Here are the top four foreign-policy takeaways from the vice presidential debate

Minnesota Gov. Tim Walz and Ohio Sen. J.D. Vance faced off in what is expected to be the final debate ahead of the U.S. presidential election in November .

The candidates clashed over Iran ’s threat to Israel , tariffs on China , border security, and border security.

The debate, hosted by CBS News , focused largely on domestic issues, including reproductive rights, health care, and gun violence.

Gov. Walz defended his travels to China as an eye-opening and informative experience.

The debate on immigration and border security initially centered on a Trump-Vance pledge to carry out the largest mass deportation plan in U.S. history.

The moderators were forced to mute Vance 's mic after he brought up alleged migrants living in Springfield , Ohio , who were granted legal status “at the wave of the open border wand”.

Walz repeatedly denounced the deadly Jan. 6, 2021 , insurrection and painted Harris as a champion of democracy.

Vance accused Harris of not protecting freedoms of speech and expression.

Vance did not answer the moderators’ question about whether he would refute a future election determination ratified by all U.S. governors.
