Donald Trump introduced a series of new proposals on Wednesday focused on defense modernization and the swift eradication of radical Islamic terror groups, while taking several jabs at Hillary Clinton, whom he cast as “trigger-happy” and “unstable.”

The Republican presidential nominee, who will join his Democratic opponent for the inaugural Commander in Chief Forum late Wednesday evening, promised to detect vulnerabilities in the fight against terrorism and guide a 50-state effort to upgrade and expand America’s military firepower if elected president.
